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.

duplicate of /questions/1358995 thread.

1. iNTRO - I spent an extra un-necessary year on the beta channel because of TBs Oauth2 set up problem. While there I had a major Tbird crash. Duplicates appearing , moving emails to other folders resulting in loss of said emails. incessant indexing, compacting and re-appearance of deleted contents of directories with unexpected loss of current contents. A real mess. After a month of this nonsense I only managed to recover by re-installing Beta to a new directory and copying backed up local folders manually, directory by directory, into the new Beta and checking (and or repairing) the contents, folder by folder. It took a day and a half. Arising from this experience and looking, sometimes aghast at the Beta Channe,l I suggest the following.

2. Suggestions 2 .1 Repair Tool We need to have a repair tool to rebuild a mail system just as I have partially described - you will know that there are many nuances in such a rebuild with some .sbd files not being recognised automatically and some others being recognised (trial and error methods were used to overcome these problems). In short you guys have the rule book and could easily programme a rebuild tool. What a relief it would be to know that such a rescue vehicle was at hand. 2.2 Back Up Tool As email data bases grow - mine is now 33 Gb - there has to be good back up system that users can trust. In the MS world (awful software) the back-up tools are not much good - so it would be useful for TB to do this or recommend some software for this purpose. I think TB guys should do this as Restore facilities are critical here - offering users options to recover particular email folders and emails and place them in particular locations would seem essential. 2.3 Archive

I have a lot of folders - but many are not  active at any one time. eg I have sent directories going back to 1997 eg Sent_1997, Sent_1998 etc . It would be useful to have a foreground / background arrangement of folders where folders in the background were semi-archived. They would be visible and accessible when required but not part of TB's routine search or maintenance .   They could be differently coloured in the LHS pane. It might take longer to access them. This might have the effect of preventing loss of active performance.

2.4 Deep Archive A deep archive where the user elects to compress(ZIP) folders in the Deep Archive. Once archived these would be ignored by the system unless they were released into the foreground /background area 2.5 Purge Command When things go wrong and the indexing screws up many duplicates are sometimes created. There should be a Purge folder command when right clicking on a folder.

There are other things such as better TB messaging and better documentation of the profile folder system - the existing information is too dispersed - and shoe-string - needs a User friendly approach not assuming one is familiar with shells. Do everything through DOS for consistency. Here too a tool would be useful.

Best

How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

Use updated Firefox as default browser on my Win10 desktop. Problem started in about 2wks: I open my cdn bank website, sign in with pw, get my banking items page, click on visa, and browser freezes, doesn’t let me open any of banking items. Now top of this page comes tiny msge: "This page is slowing down Firefox. To speed up your browser, stop this page. Stop" Even the SignOut spot is frozen! I dont care about slower speed , I am only using that website for a couple of minutes. I have to turn off Firefox, everything else in PC works ok. I tried MS Edge and the same bank website works perfectly (like before on Firefox)!!! I prefer Firefox security features, please help!!! If not, MS Edge is my default browser!!!

I made a few changes to about:config. How can i save the about:config settings for a new Firefox installation? My bet is this is possible either with distribution-policies.json or with a HTML. I used Kali Linux, this operating system comes with a pre-configured Firefox installation. For example it uses a permanent darkmode with duckduckgo even while cookies are denied. It also comes with customs about:config settings like disabled telemetry.

Those are all the setting i changed and i would like to find out a permanent way to import them to Firefox, right after installaing the Browser. It's time consuming changing each setting manually after each install...
