Форум підтримки 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?

I am trying to switch from Google to Firefox, but I still use my Google email. I uploaded my contacts from Google to Firefox, but I am trying to edit my own contact info in Gmail contacts, but when I click the edit button, nothing happens. Do I need to edit it in Firefox, and will that edit migrate back to Gmail? Why can't I edit it in my Gmail contacts (in the Gmail right-hand toolbar), and it will update my Firefox contacts automatically?

If you are going to require "A" file type, fucking say what type it has to be and provide a converter or screenshot tool! I Tried .Docx and PDF. Word does not save to PNG or JPEG so they are not an option.

AT THIS POINT, I AM STRONGLY RECONSIDERING SWITCHING FIREFOX!!!!!!

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.

Firefox 126 has changed the tabbar tab background handling and I cannot find a way to get my graphical tab background back for the selected tab. The left image shows FF 125.3; the left 126.0, which installed itself yesterday. In the userchrome for the old Firefox I have:

    #TabsToolbar:not(:-moz-lwtheme) .tabbrowser-tab .tab-content
 {
   background-image: url("file:///D:/System Graphics/Toolbar Backgrounds/rgsweeve - 000.bmp") !important;
 }
  #TabsToolbar:not(:-moz-lwtheme) .tabbrowser-tab .tab-content[selected="true"]
 {
   background-image: url("file:///D:/System Graphics/Toolbar Backgrounds/rgsweeve - 040.bmp") !important;
 }

This gave me the differentiated selected and unselected tabs but does not work for the selected tab in the new Firefox. Any ideas how I have to specify this now?

[I am making this post using the older version of Firefox. If I get some suggestions I'll reinstall the newer version (actually turn auto update back on) and try them out. Thanks.]

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.

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

• Error Message in Console: Uncaught out of memory
• Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
• System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
• Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

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.

In my Firefox email when I click on an email it opens to the entire page, but then if I want to get back to see the "Inbox" with the accounts and various folders I have created it seems the only way to do it is to scroll back on the line at the top which sometimes is short but literally sometimes takes a very long time and I don't know how close I'm getting, or I have to go up and click on the little contents box in the upper left corner, click on something else, like calendar or tasks to get out of email and then click on the contents box again and click on email. There has to be an easier way???

Thanks for any help in advance.

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.
