It's obvious from this and previous posts/topics that you have an issue in your PC with a virus, malware, or drivers, or security or speed up software that might be conflicting with Opera.
I use Opera 29 in several computers without any problems. Other millions of users also use Opera without problems, otherwise the forums would be drowned with topics by now.
Please look for something like that in your PC. Try AdwCleaner, update the graphics driver, disable/uninstall suspicious programs or antivirus to test whether the issues are solved.
Please stop spamming the forums with more and more topics about the same subject. I don't have much more time to help so I'll leave a tip: you can find some info by using a search engine, like, Google "site:forums.opera.com your_question" without brackets.
Opera does not offer bookmarks / Speed Dial export but other browsers might be able to import directly... Like Vivaldi... And MAYBE the Bookmarks file in your Profile is exchangeable with a Chrome or Chromium-based browser Profile. You can try experiment with that, if the Speed Dial isn't moved it might be a good idea to use the Bookmarks manager to move all your SD items to another folder before copying the file.
Opera 29 is insecure, incompatible with almost all previous extensions and has cut down our options and preferences to an even more ridiculously low amount as before.
None of this is even remotely true, any extensions that worked with opera 28 will work with 29... and afaik opera 29 removed no preferences or options from 28... it only added features.
I will start by saying you didn't address the auto-update issue. See, I know you think forcing them down our throats is akin to forcing a child to take it's medicine, but I am not a child. Opera worked fine, with a few minor exceptions being some of the changes from Opera 12, until I was once again caught in a lag before opera started up. It then gleefully informed me that my browser had been updated, all in an intertone as if it had done me a favor. This is why people don't like auto updates. They're often not compatible with extensions and previous configurations. So pretty please, with sugar on top...how do I make opera stop auto-updating?
If you can answer no other question, as it's beginning to become painfully clear, that I've asked or addressed in any of the problems listed, then please, for the love of god, TELL ME HOW TO DISABLE AUTO-UPDATES. Because it gets worse from here. It always gets worse from here. "New and improved" is rarely anything of the sort.
I'm not using a proxy, though I admit my ignorance of what exactly a proxy is, from my limited understanding it takes knowledge of the inner workings of the computer that I unfortunately do not possess. Also, there is no internet security software on this computer.
So much for that presumption
I'm very happy spellcheck is working for you, although as I stare at the word "spellcheck" in this sentence, it isn't underlined. AEIOU adn soemtimes Y. None of it underlined. At all.
I've just changed the format to HTML 5. Worse than before. Plays the same video twice, one overlapping the other. Switched back to the uncomfortabe view that requires a reload every time becaus that's actually far more tolerable.
Yes, I'm aware appearance options were available in 12. Why aren't the available now? The extensions that come even remotely close are all deeply flawed and revert back to the 37 hiroshimas of light that is the near death experience brightness of the hideously white Google background, among others. I just threw this question in there because seriously, it was very convenient. It wasn't good with certain pages but it's better to uncheck the high contrast option once ofr twice a week compared to having to press and darkening button for every website you visit.
You're ruiining your browser.
Yeah, I got both of those add-ons. I've tried everything but they're a pain. I just got done working with the new Firefox today and got everything all set up to my liking and then...friggin' thing's giving me a headache trying to play videos, it has the same problem the old Opera 12 had when you don't let the webpage choose it's own style, you can't see picture/thumbnail links...
The internet's ruined, lol. It's just ruined. Part of it's a personal problem, my eyes have just grown ultra sensitive to light. The night/day extension just dims the page a bit and makes things hard to read. Night mode does what I want it to do but every time I go to a new page it resets to nuclear light blast mode. I feel like a Nagasaki citizen. My shadow's burned into the wall. My skin is melting...melting...
So if I have to choose between the 2, Firefox blacks everything out automatically and I just occasionally, whenever I watch vids or go to sits with pictured thumnails, I have to let the webpage choose their crappy style. Which is usually just...radiating. Very Hiroshima.
I made an appointment with a doctor for next week. See if there isn't anything she can do or recommend. Maybe its time to get glasses or something. Anyway, like I said, you guys had it almost perfect. I'd still be using Opera 12 but sites are literally rejecting it and closing the browser on me. I guess it's that outdated now.I just hate juggling 6 browsers. If I want to do one thing, I use firefox, another I have to use opera. Sometimes I have to fire up the older browsers just for convenience, and I have pale moon for the hell of it, but it rarely gets used. There was one major thing about the older browsers that made me keep them, but for some reason it's just slipped my mind. I blame having google as a homepage. It starts up like THE BIG BANG and instantly fries what little braincells I have left. Oh, that's right...I can search in google uncensored. Very important since they because the search gestapo. I tried bing...still hate it. But it's improved, slightly.
As I'm sure you can tell, it's driving me mad.
You know what add-on would be great? An add-on that takes me back to 2004 when all this crap wasn't necessary.
