How to disable right click context menu option: close other tabs, close right tabs ?
When i only wanted to close one tab i closed too often too many tabs by mistake.
The mouse pointer can easily be misplaced in the opera context menu because all close options are too near together.
Either way i do not use the options of closing many tabs by mouse, so why not disable these dangerouse options in the context menu?
thx

The Service Worker, Webworker-Case : Where too much RAM+CPU+HD+Internet-Traffic usage could be caused by.

I wanted to make a backup of my Opera Browser profile folder, but it seemed to be too big with over 1 GB. So i searched for reasons. The Cache etc. are normal space consumptioners.

Look for yourself how big them Service Worker folders could explode!
C:\Users\Your Profilename\AppData\Roaming\Opera Software\Opera Stable\Service Worker
Mine were over 400MB!
For an Opera Browser profile backup much too big.
After DIY cleansing they got 60% off size AND Opera Browser also got 40% smaller in RAM and faster in reaction and data transfer over Internet, subjectively

It could be that many users with problems with RAM, CPU usage, Browser speed or hanging Internet should look at this case to solve them.
In my view the security vulnerability of all browsers worldwide is affected by this underestimated browser feature too. I found one case of misusing the service worker a year ago, see below.

Here is my workaround against the Service Worker "Overload".
Please amplify and correct

1. Possibility:
   File Explorer:
   C:\Users\Your Profilename\AppData\Roaming\Opera Software\Opera Stable\Service Worker
   There folders:
   CacheStorage (biggest?)
   ScriptCache
   Database
   To sort files and folders by size i use the XYplorer.

In this folders you could always read the
index.txt
to see which site (mis)uses your HD space.
So i discovered plus 100MB eg from nytimes.com, where i didn't look for years.
I deleted all at once. But this is too time-consuming for evey folder.

2. Poss.:
   Simplier with the address bar:
   opera:serviceworker-internals
   Here you can manualy click unregister per Domain.
   I cleaned all up but supposed important folders like Googlemail, Opera, etc.
   Success: More than 200 MB and 60% shrunked my Service Worker folder!
   But this won't be permanent i'm afraid.

3. Poss:
   Opera developer tools :
   CTRL+Shift+I, Application, Service Worker, Service workers from other origins.
   I did not use this.

4. Poss.:
   Deactivation of Service Worker in the Opera Browser per Addon uMatrix:
   Click on the 3 points points on top of each other to the right of On/Off: Forbid Web Workers.
   This is a stable adjustment i think.

5. Poss.:
   opera://flags
   Search for "service worker".
   Enable/Disable:

• Service worker on UI thread
• Prefetch request properties are updated to be privacy-preserving
  Could be permanent, but this seams to be too unspecific und risky for many sites who do profit from that.

Conclusion:
Options 2 an 4:
opera:serviceworker-internals
Addon uMatrix
They seem to be a good team: First delete non important and then block this permantly by an addon.
But you got to look regularly in your Opera Profile folder "service Worker", otherwise it would blow up too much.

And the problem stays that you can not simply get rid off this data waste.
Not to talk of probably important security risks.

Warning: Playing with web workers an service workers could break some pages!
Yes, for website performance or while staying offline the Service Worker might be useful and necessary, but i never read something positive about it.
Who has got sources?

What do you mean?
thx

ps: Misuse, abuse of Service Worker, Webworker!

hi.
Funktionsvorschlag:
Opera sollte bei Addons
opera://extensions/
neben Alle, Updates, aktiviert, deaktiviert
auch alle gesperrten Addons zeigen.
Zumindest bei der Anzeige folgender Meldung könnte der Name des Addons dabei sein:

"Opera hat eines Ihrer Addons auf die Blacklist gesetzt" opera://extensions/ "Wir haben diese Erweiterung als bösartig identifiziert und sie auf die Blacklist gesetzt. Dies bedeutet, dass sie keinen Schaden mehr auf Ihrem Rechner anrichten kann. Sie können es belassen wie es ist, oder sie entfernen."

Wenn man zuviele Erweiterungen besitzt oder deaktiviert hat, dann dauert das suchen danach zu lange.

Jedenfalls ein bisheriger Workaround:
Suchet nach "bösartig" per Strg+F
Dieses Suchwort muss einem nur dann einfallen...

Hi.
I can't find a page because there are only page titles to search in the Opera history
Would'nt it be fine to search also in the running text of pages in history?

A second search field on the Opera history page would do it, or a checkmark.
Opera could search existent cache content of pages and live, not to archive the whole stuff

thx

ps: Yes, i can remember some social browser over 10 years ago with this feature

@burnout426 i also ask in the German forum
https://forums.opera.com/post/190576
But there is not so much response.

Yes, Opera showed a message that it disabled an unnamed addon causing problems.
So I have no link to it.
And i do not remember the reason why Opera did so.
I missed to take a screenshot. Next time.

thx

ps: it seems i "lost" today another addon.
But silently... o_O
I found its icon on an older screenshot.
It is not listed in my addons anymore, even not in deactivated, so it got unasked deleted by Opera.
And i cant find it in addons.opera or chrome.
Who recognizes it by this screenshot?

Hi.
I often copy URLs out of my bookmarks.
But you can not copy the URL adress easily.
It is annoying to always edit a bookmark bevore you can copy its URL adress...
This would be fine to have in Opera

hi.
Several times there comes the warning "Blocked insecure content" on the reight edge of the address bar.
You can allow it or not - without knowing exactly what it is?
How could i see what contest is insecure?
Is there an Addon?
I want to choose by knowing whats theatening.
thx

Hi.
By pressing STRG+F or F3 the search field/bar in Opera Browser is flapping down from above.
But as effect the Whole page gets shift down.
This is really annoying!

By this sliding of everything visible all text is not readable and you get easily lost your reading position in the text.
This moving all pages down has no positive use.

On some pages this sliding down of the search field changes the whole layout.

Could the Opera search function please be changed with no effects on pages?
Perhaps with an overlaying search field which only covers a small region instead of shifting all.
This would be more professional.
thx

@burnout426 thx
i changed
tab left = y
tab right = x
last tab = ctrl-shift-y
all on the left hand

hi.
Opera adds news bookmarks only at the bottom in each folder?
Is there no option to change this behaviour and choose always to add them to the top?
This is missing.
I did not find any addon.

no option to add a page to bookmarks per sidebar and right click on a folder as possible on the top bookmark bar?
Why not?

How to disable right click context menu option: close other tabs, close right tabs ?

Also good:
Tab Position Customizer - Modified

But the opening of new blank tabs lasts very longer done by Strg+T than by context right click on the tabs bar.
WHY??
And with the addon Vimium closing of a tab by key x is very faster than the built in method. Why?

Opera: control of offline special website data ?
The allocated HD space for offline data from websites, not the Cache, is enormous!
opera://settings/content/all
"Von Websites belegter Speicherplatz insgesamt: 7,1 GB"
From web sites allocated space 7.1 GB !
WTF?!
100s websites save massive data on your computer in Opera - secretly !

Some pages i cant even remember to have visited them:
Used: 3,6 GB, 809 MB mozilla, 537 MB google and many more.

Question:
Is there no Opera option, addon or external App to see and control that??

More questions:
Is this a special cache for sites outside the normal cache?

This has nothing to do with "clear browser data"?
cache, cookies, history, hosted app data, ..
opera://settings/clearBrowserData

Nothing to do with Web worker, wervice worker, which also uses "secret" space on my computer?

It could be a big security leak, tracking?

thx

The Opera addon Classic Tabs is also good :
https://addons.opera.com/en/extensions/details/classic-tabs/

tags: open close new tabs next to active tab closing opening

Opera was too slow.
Version:92.0.4561.21
But i found a Solution - and and a severe Opera error?

Opera used too much CPU and Harddisk in the Windows task manager.
This also together with the "System" Task.

I looked in the Opera Task-Manager and found that "Tab Speed Dial" is using too much CPU when pages are loading.
So in options i unchecked, disabled "Show Speed Dial Suggestions" and at once it runs much faster!

This must be an Opera error because this has nothing to do with opening new tabs with speed dials.

AND System Task is quiet now too
Perhaps this could be no coincidence and is also a Windows error.

Opera war zu langsam
Version:92.0.4561.21
Aber ich fand eine Lösung - und einen schweren Opera-Fehler?

Opera verbrauchte zuviel CPU und Festplatten-Leistung im Windows Task-Manager.
Dies auch noch zusammen mit dem Task "System".

Ich schaute im Opera Task-Manager und fand heraus, dass "Tab: Schnellwahl" zu viel CPU nutzte wenn Seiten geladen wurden.

Also deaktivierte ich "Schnellwahl-Empfehlungen" anzeigen und sofort lief Opera viel schneller!

Das muss ein Opera Fehler sein, weil es nichts zu tun hat mit dem Öffnen neuer Tabs mit Schnellwahl.

UND der Windows System Task ist nun auch ruhig
Vielleicht könnte dies kein Zufall sein, sondern auch ein Windows-Fehler ?

Error on Wikipedia Left side white.

sometimes not all text is selected automatically but only a random part.
This is an error i think.
So there must be the possibility to change this option
