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

Something new is happening - there is a slow and very obstructing problem in sending emails - I can receive emails normally but when I try to reply or to send a message, a yellow bar appears telling me there is a huge content slowing my process and asks me to click 'stop' or 'wait' It now takes 15 - 20 minutes to wait to send a message This has never happened before and has been happening for two days now. Please correct this problem. Thank you

firefox crashes after closing every time

‘Firefox refuses to open, just keeps giving the message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." When I click on close, the message just comes back, I have deleted, and reinstalled Firefox, but it is still the same, I am now having to use windows outlook. Please help me get back onto Firefox.

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.

Firefox browser will not open. The FF icon is located in my taskbar (Windows 10). When I rest the mouse on this icon I see a very small representation of a website. When I click on the icon I see flash of some sorts on the desktop for about a nano second but the browser will not open.

I uninstalled FF and reinstalled. FF would open OK and I had no problems opening various websites. However, after I closed FF and attempted to open it up again it would not and so I am back to the original problem.

As I needed to access a website, I attempted to open Microsoft Edge and experienced the exact same problem. With the Microsoft Edge browser icon in the taskbar I can see a very small representation of a webpage but this browser will not open either.

Any assistance you can give me will be much appreciated, Con Van Dyk

Since a few days, I keep experiencing constant crashes with Firefox. In the most common way, a Tab will crash first, often followed shortly by the whole browser crashing. Crashes occur on, but are not limited to, following pages: • YouTube.com • Reddit.com • Google Account Login • about:preferences • about:crashes • about:support • The very same Support-page I’m writing this on Crashes still occur after: • Rebooting Computer • Clearing of Cache • Starting in Safe Mode (crashes in Safe mode) • Deactivation of hardware acceleration • Refreshing Firefox • Reinstallation of Firefox (Uninstalled with the Uninstall/helper.exe) • Use of Windows Deployment Image Servicing and Management tool (DISM /Online /Cleanup-Image /RestoreHealth)

Crash logs list: • Crash Reason EXCEPTION_BREAKPOINT Crash Address 0x00007ff88082381f • Crash Reason EXCEPTION_ACCESS_VIOLATION_READ Crash Address 0x000001f4465fffe8 I’m kind of out of options. Most support pages are 2 years or older, so I don’t really know if I’m experiencing the same errors as they did. If there’s any more information required, please let me know.

Firefox (desktop version 96.0.1 64-bit) just updated itself on my laptop. Now, it will not load any pages. I'm sending this message using Chrome.

Please help.

Browser stopped responding. Extensions didn't work. Regular reinstall left me in the same situation.

I have tried to do a clean install 4 or 5 times. Deleted profiles, went on a hunt for files to eliminate.

will do a google search 3 or 4 times after reinstall, but won't connect to other sites then it won't connect to google either. I'll get the 6 to 8 instances in the task manager that I have to kill.

Last night my firefox stopped working. Any time I used a bookmark or typed in a website, it would start to load and just sit at a blank screen continuing to load but not doing anything. I checked in another browser and it worked just fine, so it’s not my internet. I’ve tried closing and re-opening firefox, any time I open it now it says it’s already running and I need to close the previous session. I have tried un-installing and re-installing firefox, clearing my history and cookie cache, and restarting my laptop multiple times but nothing is working. I would appreciate any help with this, thank you.

No websites will load at all. The address looks fine but the loading ends up timing out just like when the address isn't correct or the site is having issues. I believe this started after the last update, I don't remember if it was a Firefox or windows update. I've tried the suggested troubleshooting tips, and uninstalled re-installed firefox twice. All I achieved was to lose my dark theme and previous open tabs.

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

When I open FF, the window only displays the top menus. If I click the Green dot it will then open full screen. Pressing the green dot once again only displays that 1 inch window. The problem does not occur in safe mode for Firefox. I turned off all of my extensions and turned off hardware Accelerator mode yet the problem still happens.

This just began yesterday and I don't believe I installed anything.

Hey!

The UK Met Office (UKMO) has a General Aviation (GA) service where they publish weather charts and such: https://www.metoffice.gov.uk/services/transport/aviation/regulated/aviation-briefing-service-guidance It's a free service, anyone can create an account.

The login page, however, has a slightly odd way of collecting the username and password: https://logon.metoffice.gov.uk/Login?goto=http://www.metoffice.gov.uk/premium/myservices/

On that page, there are two <form>s, each containing an <input> element, one for the username and one for the password. The login button is just some javascript which fills in a third, hidden form and POSTs it. Once I have logged in and Firefox has offered to save the password for me (I have to tell it my username because the forms confuse this step too), it never manages to complete both forms. It only autocompletes the password.

Is it possible for Firefox to learn how to cope with this form? I suspect convincing UKMO to fix their website is unlikely, and they're probably not the only offender...

2021, nearly 2022, and browsers *still don't support* uploading a few thousand pictures in a few hundred sub-folders! :(

i met a major disappointment this week, when i found out the one PHP + HTML5 solution for uploading more than a few thousand HD and 4K pictures to a Content Management System (plupload.com tied into my own https://github.com/nicerapp/nicerapp), just doesn't work yet. in 2021.

it is one thing that we, CMS builders i mean, needed to find a component like plupload.com which allows us to upload our pictures in 1MB chunks, then recombine them on the server, and make the thumbnail after that, but to not provide us with any means at all to get the relativePath of the files being uploaded, IS AN UTTER DISGRACE, if you ask me.

the CMS building community has been complaining about this to browser makers since at least 2014(!).

see https://www.plupload.com/punbb/viewtopic.php?id=4188 for details.

see https://github.com/nicerapp/nicerapp/blob/f6998dd03015fe8e0768b346ea7147dec314e6ab/nicerapp/userInterface/photoAlbum/4.0.0/jquery_ui_widget.3.1.3.php#L114 and https://github.com/nicerapp/nicerapp/blob/f6998dd03015fe8e0768b346ea7147dec314e6ab/nicerapp/userInterface/photoAlbum/4.0.0/jquery_ui_widget.3.1.3.php#L145 for a pinpointing of the problem..

and it's now 2/3 of the way through 2021 on the way to 2022(!!)... :(

we, the builders of apps and systems that run in the browser, need a solution for this big problem as soon as possible.

how hard can it be to properly support in document.getElementById('uploader').addEventListener('drop',function(event){...}) the functions event.dataTransfer.items[i].webkitGetAsEntry().createReader() and event.dataTransfer.items[i].webkitGetAsEntry().readEntries()?

IT IS PROBABLY EASY TO FIX, WHEN GIVEN PROPER ATTENTION AND PRIORITY!

2021/08/11 : So, i don't know if this is a plupload error or a Chrome error, the problem occurs on both Kubuntu->Chrome *and* Windows10->Chrome (for uploads of a few thousand pictures in a few hundred sub-folders), but it's up to the browser makers and the makers of plupload to fix it, as CMS builders simply do not have the means to produce a fix, let alone distribute that fix.

And one more thing : it is another disgrace that non-webkit browsers don't support the relativePath functionality at all.

THIS MUST BE FIXED, AND SOON TOO PLEASE!

i'll now post a link to this post on the various browser makers' support forums, and list those links in a comment to this post at stackoverflow.
