After the second to the last update to Firefox I started experiencing an information pop up message "Could not determine any profile running in backgroundtask mode!".

Is there a fix for this?

Thank you.

Hi, we have 4 PCs (3 running Win 10 and one Win 7) which updated themselves today and lost everything. Settings, add-ons, bookmarks, shortcuts all gone; looks like a new install. I checked the other threads and the profiles; there is only one profile and no backup. How to get my stuff back?

After moving to Firefox 91.9.1esr I found problem with System theme 1.2. The color of tab add button was changed, and the button is not visible with my Windows 7 classic windows system theme. So, I'm trying to find a way to port System theme 1.0 color scheme to newer firefox versions.

Creation of a simple theme with firefox color extension works. But it is unable to recreate the effects related to active and inactive window color changes. As, I had to use bitmap to get the OS blue color transition pattern.

It seems the system theme is stored in omni.ja file. Modification of the omni.ja seems to be not a practical solution. So, it would be a better way to create an addon theme with the same code as the System Theme 1.0.

The first question is, if it will be possible to create a theme with the same code as a system theme has. Will it be able to perform the same way?

The next question is: Where the source code of the system theme is? I was unable to find it in the Firefox source. It seems, it is not stored in any obvious location.

Hi, this site when trying to login keeps looping, it has only happened recently and I've cleared cookies and disabled all the addons for it, the site works, but when trying to login it loops https://www.nexusmods.com and says in the loop-

users.nexusmods.com

Checking if the site connection is secure users.nexusmods.com needs to review the security of your connection before proceeding.

even tried in private browsing, cannot use any other web browser. Please help thanks.

I just downloaded firefox and this is not like the older version,hard to navigate,it tells me to click firefox ball,upper left corner and click options options is not there. I want to xfinity to open when I start firefox,I want to know where to go and how to do it

I prefer to update Firefox manually, so in my Firefox settings, I have it set to: "Check for updates but let you choose to install them".

So I sometimes get a message when I launch Firefox saying "Update available. Download the latest version of Firefox." and I click "Dismiss"

Today, I launched Firefox (v107.0), got this update message, and clicked "Dismiss". However, when I go to About Firefox, it says "Firefox is being updated by another instance".

Why is Firefox ignoring my preference?

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. How do I NUKE this permanently?

I already have telemetry and automatic updates both turned off.

A related problem is that the About Firefox window keeps saying "Firefox is being updated by another instance", even though I always "Dismiss" the prompt to download the latest version. (I'm using v107.0.)

Since the update to Firefox 107.0 (now on 107.0.1) from 106.0.5 on two Intel-based Macs with Intel integrated graphics running Windows 7 (I know...) under Boot Camp, I'm experiencing poor graphics performance in Firefox. I first noticed this when scrolling felt choppy and then subsequently on video playback (YouTube and other sites). Text input and other animations can also feel more laggy or jittery than previously.

This is very similar to what I first experienced when WebRender rolled out to these devices. At the time, I set gfx.webrender.force-disable=true. However, I believe that setting hasn't been heeded for several versions, so I was eventually using WebRender without issue. The release notes for 107 do not suggest that anything related to WebRender or compositing have changed, which makes this particularly baffling.

The amount of stutter is compounded after opening a second Firefox window (regular or Private Browsing).

I have tried Troubleshoot Mode with extensions disabled and disabling hardware acceleration, but the problem occurs in either mode (confirmed with about:support showing "WebRender" or "WebRender (software)" as appropriate).

I enabled gfx.webrender.debug.profiler=true to examine frame rates. Shortly after launching Firefox, frame rates remain around 60 fps and things feel smooth for a bit. However, the frame rate will periodically drop to about 22-31 fps for 5-10 seconds while playing a video or continuous animation without interaction. Viewing Task Manager for all users during this process does not show a notable spike in activity for other processes when the frame rate drops and overall CPU load is nominal.

Opening a second window causes the frame rate for all windows to drop to 30-31 fps maximum, which similarly periodically falls to 12-15 fps for a few seconds. It's clear that the target 60 fps is not maintained when more than one Firefox window is open. I had not checked the reported frame rate with a second window open in prior Firefox versions, so I do not know if this is a change, just that I hadn't observed an apparent degradation in regular use.

The two graphics cards in question for these two machines are: Intel HD Graphics 3000 Intel Iris Pro Graphics 5200 I believe both are updated with the last OEM (Apple) Boot Camp drivers for this hardware which, granted, are on the old side. I have not yet attempted later drivers directly from Intel, as I hadn't encountered issues until this recent Firefox update. I have not noticed an issue on my other machines running Firefox.

Any suggestions on restoring the graphics performance would be appreciated.

This must have been designed by someone with SERIOUS brain damage. Every time I use it it shows its glaring deficiencies. Its like whoever designed it never used bookmarks before in their life and never used it after it was done. I use the term "done" very, very loosely. How can people like this get work?

When you add a bookmark a narrow window opens up (of course you can't resize it) but I wonder if I can change its size in about:config? If you have a lot of folders you can only see a tiny bit of them at once. Its just ludicrous.

Another bizarre thing about the Firefox bookmark system is when you click on a bookmark it overrides your last opened tab. Why on earth would any sane person do that? If you want to close it you can close it anytime. Is there something in about:config that can make it work properly?

Maybe there's an extension with a sane bookmark system that doesn't look like it was designed by a brain damaged nutcase?

Maybe its just an autistic thing. Brilliant in a few areas and totally out to lunch in others. Like common sense. Sorry to be so harsh but I cannot comprehend how Mozilla has not fixed this. Maybe they left Earth and are exploring other worlds.

Yeah I know....I need a bookmark program. Its just kind of convenient to have it built into the browser sometimes. Its more seamless. If only this wasn't so bloody awful. And I do mean bloody.  :)

If only I was smarter so I could code myself.....

First, this post is basically Congratulations for Firefox upon working almost flowlessly under this extreme heavy load without crashing. Saving/loading sessions works well. (which is unexpected but makes me _very_ happy :-)) Firefox exits properly without any exceptions, no matter how long it runs, or how many times the PC is sent to STR mode meanwhile.

Second, everything is fine, except RAM usage. No matter how many RAM is installed, Firefox takes up all of it after a few days of normal operation. I have recently upgraded my PC from 16 to 24 GB of RAM only for this sole reason to see if anything changes, but it did not produce any noticable change, except that it takes 5-7 days for Firefox to fill up all the RAM instead of the 3-4 days before. Disk space on C: drive was nullified by Firefox as the paging file went up to 50 GB.

I want to hunt down this thing. I have approx. 300 tabs, 2 addons, and Hardware Acceleration is disabled since otherwise Fox hangs several times a day (have to be killed from outside). Pics are attached. https://addons.mozilla.org/hu/firefox/addon/tree-tabs/ https://gitlab.com/kroppy/TreeTabs

I'd like to get suggestions where to start.

1. Disabling or replacing the adblocker ?
2. Inspecting memory usage on Process Manager (about:processes) and Task Manager (about:performance) pages ?
3. Installing some external tools like Firemin ?

Please don't suggest neither safe mode nor disabling all addons, since that makes it impossible to reproduce this amount of load, which is the primary reason behind the symptom.

I PrtScr'ed Process Manager and Task Manager, see that RAM sizes per page are normal in Task Manager, but not in Process Manager (10 times more).

CPU usage is totally normal for this load, even when memory is in the heaven. See the TaskMan pic. (I suppose that's because of ad blocking)

Thanks for any ideas,

I can no longer sign in to my account at https://www.therich.io/en. When I click "Sign in" nothing happens. It used to work fine. I can sign in with Google Chrome no problem.

What can I say to Fifth Third to persuade them that I am not the problem? They get plenty of complaints from others with my same problem, according to customer service there. Is there a way for me to use my computer, my browser of choice, etc?

last sunday when i restarted my pc due to sluggishness with mozilla firefox and thunderbird, a problem occurred to disable the functionality of bookmarks (favorites) and history; an error message pops up saying one of firefox's files is being used by another application, caused by a security program.  as a result, pressing control shift o for bookmarks library shows an empty tree view; typing a search entry in the editfield yields no results-bookmarks have all disappeared or are inaccessible. also i can't save a new bookmark with alt control d. later on i noticed my firefox browser had automatically updated, so this may be responsible for disabling functionalities of earlier firefox versions; i currently have firefox 107.0.1 on windows 7 machine.  does anyone know what i can do to re-enable the bookmarks functionality like it was before, and how to turn off automatic updates?  thanks.

Dear Sir

1: Firefox often crashing. 2: When I opened a site (mail, youtube...what ever it is ) it said No responding I could not close it I could not go anywhere, the only thing I did was shut down computer completed then waited for 5 or 10 minutes to turn on PC again. 3 : The pages (site) I was watching it just gone (for not knowing why?) I then have to open it again from start.

The problems happened so often in recent months. It's really frustrated, annoying, and fed up. Can Firefox engineer help to sort out these problems. Please.

Thank you. Louise

Some web pages contain data split into pages and provide something like "Previous 1 2 3 4 5 6 7 Next" at the bottom of each page. One example is https://support.mozilla.org/en-US/products/firefox?as=u&utm_source=inproduct#search I would like to be able to move between pages without using the mouse using a keyboard shortcut.

Is there any way that Firefox could simulate a mouse click on a particular element and link this to a key?

As a privacy-conscious user, I always worry about the 'Save As' dialog, and especially the 'Upload' dialog.

I know the Upload dialog enables websites to perform certain operations of files without even uploading them.

Can anyone please clarify: How much access to my computer do these dialogs give websites? Can they see all the files in the selected folder, even files I haven't selected? Can they look inside sub-folders, or even the parent folders? Can they tell the full path of the directory? Do they know my PC name?

I want to be sure.
