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.

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.

Sometimes a box pops up on the screen that asks if I want to block or allow something. Sometimes I have no interest in doing either, and just want the damned dialog out of my face. The page seems to work otherwise, but the stupid browser keeps the dialog over top of things, and clicking outside of it, and hitting Esc, don't make it go away. I think those actions used to work, and I think there, sensibly, used to be a dismiss option, but that seems to be absent now. There's no sense to trying to force me to make a decision I don't want to make, and doesn't even need to be made, and I want this thing to cut it out.

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

Firefox seems to forget edits made to text boxes. I was reading a large pdf and adding notes to previously made text boxes. I thought I must be going crazy as I saw there was no notes I thought I had already made multiple times so I tested it. I edited a text box, scrolled a bit and continued browsing on another monitor. Checked in a minute and boom edit gone. If anyone has a solution I'd appreciate it as I have been using Firefox PDF editor for a bit and quite liked it until now.
