Hello!

A few hours ago I noticed that my Mozilla Firefox was jamming a bit, at least the window I was surfing the Web on.

That session had many windows open, and most of those windows had dozens of tabs in them.

So, since my PC had been on for several days and, as I mentioned, Mozilla Firefox was starting to acting up a bit, I decided to give it all a rest. I opened the Windows Task Manager and I voluntarily "crashed" Mozilla Firefox from there, then I shut down my PC and let it rest for two or three hours.

When I restarted my computer and I opened Mozilla Firefox, I was obviously asked if I wanted to pick up where I left. So, I restored the last session and all the windows I had open came up again... except the one I was working on when I decided to shut down my PC! It was the most important window, with HUNDREDS of critical tabs in it!

Why hasn't been restored along with the others?

Is there a way to make it appear again=

I'm flabbergasted, please, help me!

Thank you,

Amalia

Hi, when I visit some websites, the pages do not work properly. The page does not want to upload properly and links on the page do not work. Can't log in to a page I have the latest version installed.

Something changed a couple months ago where Firefox's spell check began only catching about half of my typos. Over the last 15 years I have become used to my browser providing spell checking services, looking for the little red lines to point out my mistakes, so now that this feature has stopped working reliably I am constantly submitting items with embarrassing typos, having to go back and edit almost every single post I make after the fact. Is there any way to get this working properly again? Thanks.

I am trying to sync my two computers together and I now find one of them is effectively locked out because every time I try to sign in I get the message - "Blocked by content security Policy" so how can I fix this?

On Microsoft Edge, whenever i type the first letter of a word it will suggest automatically the recent words that i have use. How to enable it on Firefox, i already browse the settings? I really need it on my job specially doing reports. We can only use Firefox to access our websites.

Follow the dialog at homelink.com to report an error with a garage door remote problem. Clicking on "Submit" gets a 404 error. I've had similar problems with other website dialogs, but usually the link is just ignored. For example rockler.com, when attempting to place an order - nothing happens. In both cases, switching to MS Edge works correctly.

FireFox Developer 99.0b8 (64-bit) on the "aurora update channel" on Windows 10 PC (version 1803, build 17134.2208)

I notice whenever an update is pending (the green dot appears in the icon for the "Open Application Menu"), FF becomes unresponsive in a way. When it happens: It does not totally freeze. I can select/switch between existing tabs & scroll thru their pages. I can close tabs. I can open a new empty tab. But I can't load or refresh any pages. The only fix is to do the update, and re-launch.

Since the developer edition gets updated frequently, it is a pain.

I like the Developer Tools! But... How can I scale back the FF "update frequency", or "change the channel", so updates are, like monthly at most?

thank you.

The title already says it all. Whenever i have some sound or video running in any tab, clicking on certain things like other videos or animated stuff in the same tab or another one causes a small interruption in the sound/video. Clicking a lot of times results in sound and video stuttering. I does not appear when i just click another link.

I already tried updating firefox, reinstall firefox, even downgrading firefox. This problem only appears in firefox and only on this device. I would be very thankfull for some advices, because this is really annoying.

This is the third time I've lost all my passwords (and logins) since the beginning of the year. I had over 200 when I lost it the first time. I've entered over 75 since then and today I just lost those. Fortunately, I had a backup of my profile. The old "key4.db" and "logins.json" files I had didn't work, although they have a significant size. In fact, looking at the "logins.json" using VS Code I see the logins are there but they don't display in the "Settings > Privacy & Security". How can I get access to them when this happens again. I was able to restore the profile from several days ago so I'm not completely in trouble.  :-)

On the news web site I regularly follow videos are not displaying correctly for a long time now - they start and then freeze. In addition, from time to time, embed video content is not existing. I would like to underline that the content is appearing normally when I use Microsoft Edge.

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

After experiencing some problems (saved tabs being empty, menus gone etc.) I read about restarting into troubleshoot mode ("Help"-"Troubleshoot mode" menu) which solved those problems (I believe "Troubleshoot mode" might be the same as "Refreshing" Firefox, from what I've read -correct me if I'm wrong) . I'm on Firefox 98.0.2 on a Mac.

Following that I quit Firefox and opened it again the normal way which I assume means it went into the normal mode as before, but I realized all my extensions were gone! Reading through some older postings I see they're in a profile named "legacy_BAK.profile", and in addition I have recent Time Machine backups, so any files aren't lost, but I guess the simplest way to fix this is to re-install my extensions -but most extensions (inside the "extensions" folder within the profile folder) only have a cryptic numbered name with and .XPI extension. So how can I find out which extensions I used to have, and better yet -is there a quick way to just install everything back again with a single click (installing it from the legacy profile folder, or just moving something over to the new folder etc.)?

After a new email notification sound plays from Microsoft Outlook, https://outlook.office.com/mail/, Firefox has a constant audio stream in use, preventing Windows computers from sleeping.

How to reproduce: 1) In an Admin Command Prompt, execute "powercfg /requests" and verify nothing has a power request, especially "SYSTEM: None." 2) In Firefox, open a tab and login into a Microsoft Outlook account at https://outlook.office.com/mail/. 3) Wait for a new email which triggers an audible chime. 4) In the Admin Command Prompt, verify "powercfg /requests" reports "SYSTEM: [DRIVER] <audio-driver-specific-string> An audio stream is currently in use." Note the computer will never go to sleep due to this request. 5) Close the Firefox tab with Microsoft Outlook. 6) In the Admin Command Prompt, verify "powercfg /requests" has no power requests, especially "SYSTEM: None". Note the computer will sleep after the idle period as expected.

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.

Is there any to make Firefox automatically restart a new session (loading the start page) after a crash, without any prompts?

Context: This is for a disabled person who cannot use input devices: I start her computer every morning before going to work and load a long Youtube playlist of videos, so she doesn't have to do anything. But if Firefox crashes 5 minutes after I left, she cannot restart anything herself and has to wait until I come back.

Any ideas?

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?
