... No, I have not tried other browsers yet. And I'm not sure if I will: Chrome is buggy, outdated and dangerous, even perhaps infested; my Opera 36 gets me BSoD every exit now; the Good Old Opera 11 I won't even try; my Midori is, too, outdated, and even then when I used on OperaForums it had layout issues. So, perhaps Midori would be the only one I could try, but - considering it already had layout issues ...
You're up against a shrinking software availability selection, due to XP's increasing age/obsolesence. Many of the chromium-based and Firefox-derived browsers that are still updated will be deprecating their XP support by June 2018. The few remaining XP-specified candidates that offer some hope and hints of longer-term support and that might be worth installing and trying against this site are:
Advanced Chrome Custom-build (54.15.5320.0, based on Chrome, 3/13/17)
Slimjet 10 family (10.0.13.0, based on chromium 50, 2/8/17)
Otter - still in pre-release (0.9.92 release candidate 2, based on Qt, 11/1/17)
Lunascape (188.8.131.52563, based on 3 engines - but its Trident engine may be problematic, 5/27/17)
Even with these browsers, there are no guarantees regarding how long they will stick with XP-compatible updating, since the work and patching required to keep them secure and current will become ever more complex as chromium and Firefox engines further evolve without their own internal XP provisioning. One thing that will eventually cause problems for any browser on XP will be loss of browsing compatibility with secure SSL websites that are increasingly migrating to eliptical-curve cryptography - XP can't handle it in support of installed browsers.
Thank you, Black!
I had to go to the hospital for the third time now: yuck leaking in quantities and t~39C when I was admitted, phlegmona. The new, third doctors sliced me and diced me, now I'm more than a week home, kinda good. The fracture had already started to heal, however pathology must have remained in the bone, they removed the gypsum on the first day, now I wear a soft fixture instead. Certain muscles have grown "jammed" though due to this prolonged immobilisation, so here I've a dilemma: 1) I should move and exercise the arm, 2) I should keep the arm in the fixture.
Awaiting a pass to see some special doctor in that special clinic in Moscow again - kinda. Should check on it every day, or every other day - as the "welcoming" doctor here in the policlinic/ambulatory said I could have my dressings skipping a day cause the wounds are dry and have been for some couple of weeks.
I just add what I told about Chromium licences in Firefox in 3rd post of this topic:
I don't know why I have a memory about Chromium license in Firefox.
Currently, there seem to be 7 web browser engine variants still under active development: Gecko (Mozilla Firefox), Edge (Microsoft), WebKit (ancestor of Blink - Safari), Blink (Chrome, Chromium, Opera & many others), Goanna (forked from Gecko - Pale Moon), KHTML (ancestor of WebKit and Blink - Konqueror), and Servo (Mozilla experimental). Olde Opera's Presto has joined a growing number of dead browser engines no longer being developed by anyone. When one boils down the ancestories into families, there are really only 3 unique families of browser engines still under development: Gecko, Edge, and Webkit/Blink/Goanna/KHTML (with Servo yet to see the light of day in the non-lab world).
There's a reason for the small number, and it has to do with the costs of engine development and continuing support in a rapidly evolving Internet world. You were correct earlier: the smaller the array of engine choices, the more limited will be the feature sets compatible with the engine API's, hence the more similarities between browsers built on in-common engines. Unfortunately, that observation will make no headway against the economic pressures acting against totally new engine development. With the entire Internet model now built around 'free' products and services, browser/engine development and support costs will continue to exert irresistible pressure for browser makers (like Opera) to adopt already-existing and supported engines. At this point, all users can do is make the best choice for themselves from within the universe of available browsers. We can look back fondly at this or that feature set or capability of browsers no longer in production, but at the end of the day, we must deal with the world that is, not the world that was.
