I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Hello, please could you check, what might be causing crashes at start (even in safe mode). I have sent several reports:

When loading a page from a domain I haven't recently visited, it will almost always return the "Server Not Found - Hmm. We’re having trouble finding that site," error message. If I reload the page, however, it will load. Sometimes I have to reload 2-6 times before it works, but it always eventually succeeds. When it does work, it often times fails to load certain elements like fonts, images, embedded videos, and occasionally whole stylesheets--things that often require calls to third party domain. Again, reloading the page (sometimes multiple times) will cause the page to load properly.

I have already tried:

• Different browsers on same computer (issue does not occur)
• Firefox on different computers with different OS on same network (issue does not occur)
• Cleared cache (issue persists)
• Troubleshooting/safe mode (issue persists)
• Deleted prefs file (issue persists)
• Disabled DNS prefetching (issue persists)

This started happening 2 days ago (firefox nightly) Here is a video of the issue (forgot to remove audio tracks before recording oops): https://youtu.be/Vc5ktXUw72E

Firefox has completely stopped working on my laptop and literally the only thing I can do is open it up. If I try to go to a website, go to the settings, go to the reset Firefox page I get a white screen. I've tried:

• Resetting Firefox (couldn't make it there)
• Uninstalling Firefox and reinstalling it
• Uninstalling Firefox, deleting all of the Mozilla/Firefox files on my computer and reinstalling it

Is there an anything I can do besides reinstalling Windows?

I updated my Mozilla today and, after I closed it the last time, it just won't let me reopen. It shows a warning window saying: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I even shutted down and restarted my laptop, but it keeps giving me this same message when I try to open Mozilla. I unistalled, reinstalled... still the same warning.

Tried both close and cancel buttons, none worked to change a thing, nothing happens.

Hi. I love FF, but this has been a bad week in Moz-town.

I use two Mac systems in parallel, with identical settings/prefs, one of which is revealing a huge Firefox bug with gmail / google docs.

My MBP (OS 10.14.6) is running (pre update) FF 90.0.2 and totally fine. Everything runs and formats normally.

My iMac (OS 10.12.6) is running the recently updated FF 91.0 and all my google environments suddenly went to hell.

I'm a heavy google docs / gmail webmail user, and the latest Firefox update broke all the formatting. Dark mode doesn't work in gmail. Ugly frames on menu buttons. Google drive formatting looks like it's 1998 all over again.

Even uploading images to this support window in FF got the spinning wheel of death, TWICE. I had to switch to Safari to submit this report with BEFORE/AFTER images.

Anyone else seeing these issues? Any suggestions?

Many thanks.

-Dave

I have most recent release of Firefox and also just updated MacOS to 11.5.2. After updates the histograms on the Wordpress blog stats page do not display. They display fine on Opera. I did clear cache — that didn't help. I quit Firefox and restarted — that didn't help. Firefox version for Mac version 91.0.1 (64-bit).

I assume this must be a Firefox bug, but am open to suggestions on how to fix the problem.

Also, when I click the checkbox for "Email me when someone answers the thread" it will not accept the check. Irritating.

firefox crashes after closing every time

Hi: I'm using Firefox 91.02. It works great until I sign on to https://facebook.com.

At that point not only can it not handshake, but all my other tabs and links no longer work. I have to restart and then everything is fine, unless I click on FB.

My system is well protected with AVG.

Can you please advise?

Thanks. David

I frequently use the site SAM.gov to look at US government solicitations where documents are posted for the public to download. Recently the links to those documents fail to load on Firefox when it did just a couple of weeks or less ago. I am now forced to use MS browser just to see those.

For example go to https://sam.gov/opp/81551b02dd2d4e2b8fc06ce327d57113/view look for "Attachments" about 2/3 of the way down and you can see the circling caterpillar thingie where the links should be.

is there a setting or fix? Thank you in advance

Since the upgrade to version 93 many times Firefox freezes (blue circle moving on screen) and the complete screen is filled with the browser in such a way that the Windows tray is not visible. This is particularly being done when several pages are open in the browser simultaneously. Sometime after this freeze the browser closes itself without any notice. This is rather annoying when I am in the middle of a work.

Here are the details of my OS: https://pastebin.mozilla.org/DkNG2o5X

Please find attached a picture what can be seen when the above freeze happens.

In my "saved addresses" list under the Privacy and Security section of Firefox Settings, there are two addresses of people that have never used my computer. One formerly went to my school, and the other is a stranger. I can think of no way that they could have had access to my account at any time. Are there any other possible explanations for this?

Problem: Firefox glitches a lot if the total number of all tabs exceeds 4129, and the sessionstore.jsonlz4 file in the profile has a large size.

Details: Some interface elements stop displaying normally after some time after opening 4130 tab, 4131 tab or more - popup menus, extension menus, Firefox menus, contextual menus, hovering popup windows, etc. They're either not displayed at all or partially displayed. The problem is purely visual - these elements are present and can be clicked on with the mouse, they just aren't displayed correctly. The more tabs open after 4129, the faster and harder the Firefox lags. When I quickly open more than 50 tabs after 4129, the browser usually stops displaying anything and completely freezes. The problem also appears some time after restarting the browser. Closing all tabs above the limit of 4129 completely solves the problem.

What have I done to solve the problem and what isn't working:

• tried running the browser in "safe-mode" (without extensions and hardware acceleration);
• tried running my firefox-profile in a new clean firefox client of the same version (87);
• tried running my firefox-profile in a new clean firefox client of the latest version (94);
• tried running my firefox-profile on another computer with significantly more RAM (32GB);
• tried running my firefox-profile with sessionstore.jsonlz4 saved earlier (a week earlier)
• tried running my sessionstore.jsonlz4 in a brand new profile;
• combinations of all steps above.

Partial solution: The problem is definitely related to the sessionstore.jsonlz4 file from the profile. But since this file is critically important to me, I can't just create a new blank one. I tried creating a brand new one based on the old one, but smaller in size (I used [this](https://addons.mozilla.org/en-US/firefox/addon/sidebery/) extension). The old sessionstore.jsonlz4 (A) is 10.2MB, the new one (B) is 631KB. This difference in size is due to the fact that the new file doesn't contain data in the "image" attribute of tabs. In old (A) sessionstore.jsonlz4 67% of the space was taken up by the "image" attribute (it seems to be responsible for displaying the icons on the tabs), 16% by attribute "csp" (no idea what it is), all other attributes take less than 2% each. There're no "csp" attribute in my new (B) sessionstore.jsonlz4 and "image" attributes are "null". The first and second place are the "url" (23%) and "title" (19%) attributes respectively. I moved the new (B) sessionstore.jsonlz4 to the old profile and the problem was solved (the 4129 tabs limit disappeared). However, since the new (B) sessionstore.jsonlz4 has no "image" attribute data, all tabs are displayed without icons. I wrote a simple python-script that decompresses sessionstore files into json format, then copy "images" attributes of the old (A) sessionstore.json into the new one (C), and then compresses this into the new (C) sessionstore.jsonlz4. The size of such a compiled file is 6.82MB. When using such a sessionstore (С), the tab-icons are displayed, but the problem with the limit of 4129 tabs appears again. So it's obvious that the large size of the sessionstore.jsonlz4 file is the root of the problem.

My questions: 1) How do I fix it? Obviously, the "do not use more than 4129 tabs" option is not suitable for me. I know that most users will find this number of tabs excessive and suggest using bookmarks, but it doesn't work for me either. Spread tabs across multiple profiles or even browsers? I'm afraid that's what I'll end up having to do. 2) Why is this happening? I read people online who had sessionstore.jsonlz4 over 50MB and had no problems. 3) 67% of the space in my sessionstore-(A) is taken up by images, and many of them are repeated 100-300 times - a colossal waste. In total, I counted 792 unique images. Question - is there any way to modify sessionstore.jsonlz4 to significantly reduce its size, but still leave the data about these images? I tried to create 792 files with these images on my disk and replace the "image" attributes data with the path to these files. I tried the following options:

 "image": "D:/some_dir/123.ico"
 "image": "D:\\some_dir\\123.ico"
 "image": "file:///D:/some_dir/123.ico"
 "image": "file:///D:\\some_dir\\123.ico"

But it all doesn't work - the browser just replaces all these values with "null" after loading. In the original, such an attribute usually looks something like this:

 "image": "data:image/png;base64,iVBORw0KGAAAf8...(many bytes)...5ErkJggg=="
 or
 "image": "data:image/ico;base64,...

Any other ideas on how to replace those long data:image-strings?

I'm sorry for such a vague, long question, but I really need help from the experts.
