Diễn đàn hỗ trợ Firefox

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

When I restarted my PC and opened Firefox only 1 tab Open previous windows and tabs. All the other 6 disappeared. I opened 3 additional tabs, closed Firefox, and reopened Firefox and only the one same tab was there from the previous session. Why does the feature not work properly?

Getting application errors on some sites – but the same site works in other browsers. This has been happening over the last couple of weeks – getting application errors on some sites but not in other browsers. On the example shown I see the login page flash briefly then replaced by the error.

Windows 10 professional for workstations Firefox build 126.0

My browser auto updated today and after the refresh I found that the history under the address bar has been broken. It now displays only in part and over top of the address bar itself which as you can imagine is unusable. See image attached.

I entered troubleshoot mode and the problem went away. So I disabled all my extensions and addons, but the problem persists (when not in trouble shoot mode)

Any idea what could be causing this? It is hampering my ability to do my job.

After the latest update (Monday) my Lastpass extension icon disappeared from the extension toolbar. It was still listed in the Add-ons and themes page. How do I get it visible again? I've tried to right click the Lasspass icon but "pin it" does not appear. I've deleted the extension, rebooted and reinstalled with no difference.

Hello, all the sudden, news site comments don't show and after research here I learned it might be enhanced protection tracking settings. I tried all the settings and nothing seems to work well (not tech savvy). Strict = user comments blocked and all the other settings allow so many ads they cover content and/or there are a hundred on a page. On a desktop. Any suggestions would be appreciated. Thank you very much.

Hello. I have an issue with Firefox. Last week Facebook stopped showing images when run on Firefox. These are in the Feed and photos, etc. I tried refreshing, clearing cookies, history and cache. I changed enhanced tracking but nothing stops this. Are there any suggestions to repair this or could it be a bug? I work on Windows 10. Please help.

Thank you.

Trying to use this site: https://www.asraymond.com/mechanical-wire-springs/compression/spec-metric-compression-springs-131626/?Imperial=false

Near the top of the page on the right hand side you can switch from imperial to metric units. The link is set to metric values, but the search input is still using imperial dimensions (see this on the left side of the page as you scroll down) But it works in Chrome!

The is one a myriad of problems I have encountered with Firefox. My installation at home frequently stops searching. It won't perform a web search. Typically when I fire up Chrome in frustration to this constant event, Firefox starts working again. I have removed and reinstalled Firefox, but this did not solve the problem. It's my understanding the Google finances Firefox. Are these problems intentional?

My computer has been having some problems lately: Any rough handling might trigger the computer to shut off instantly or restart automatically. This is likely a hardware issue, probably a loose battery or something. The Firefox-related issue is that sometimes, upon turning the computer back on, something odd happens to my browser session: It is set back to three months earlier. The recent browsing button show everything having been browsed three months ago; but when I check my history, all my most recent tabs are there. This is tedious whenever it happens, as I have to spend about an hour manually opening everything I've lost (that I want to keep) from history. If there's a way to bulk re-open a bunch of tabs, I don't know how. All that has become something of a routine annoyance (it happens maybe once every two months) but I'd gotten used to it and it wasn't really an urgent problem. Today, however, I dropped my phone on my laptop, triggering a restart and a blue screen with a message that said something like "we're cleaning things up for you." It's what usually happens when I drop something on or accidentally elbow my thinkbad. (More commonly I move my computer a little bit and it just shuts off completely, goes black.) Before this happened I was due a firefox update, and I found it had done so when I turned my computer back on. I realised immediately that I had lost some tabs, and I assumed that it was just a three month setback. Upon opening my recent browsing though, I found out with horror that I'd been set back nine months. I cannot restore from a nine month period manually. I don't have the time, energy or willpower. I'm asking here if anyone knows how to bulk restore tabs from history or how to restore my session to how it was just a few hours ago. Thanks

Today while using firefox all my open tabs and windows crashed. Due to the situation, I had to restart my computer because everything was stuck. When it restarted I couldn't restore the previous session so I used various methods to restore it but I still can't restore the windows and tabs that were open today. I would like you to restore my session from before the failure today.

I have looked around the Internet for similar issues, but most of them appear to address the moronic F11 full-screen problem. I'd be grateful to know if a 'tabs bar' option remains in FF126, and if so, how to enable it. Many thanks.

I have search and have seen screen shots. But not actually how to do it. In firefox the Application Menu "the three lines or the Hamburger." How do you move it to the Left side of the screen instead on the default location on the top right. Also please correct me if this is not possible. And thank you in advance. I am on the latest version and currently using windows 10.
