Firefox Support Forum

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

When logging in to the online bank at DNB with Bankid, this error appears:

"A communication error has occurred. We are experiencing a communication error between your browser and the user site. The reason may be slow internet or problems with your browser. Try again in a little while. You can also try to delete cookies and browser data in your browser or try a different browser. Error code BID-5000 Reference DXP4VKOE Date 12/06/2024"

No other browsers show this error. I've tried Edge, Chrome, Vivaldi, Brave, CC Cleaner. The error starts after version 125.0.3. Today a new version 127.0 arrived. The same error appears.

I have uninstalled the latest version and reinstalled version 125.0.3. Then no error message appears. I have deleted cookies and browser data, but the error message persists. To your info, I've tried also on other PC's and the same Firefox version, and the same errormessage appear.

I look forward to you having a solution to the problem, otherwise I will have to use browsers that do not show this error. As I prefer Firefox, I don't want to use other browsers. But if the bug can't be identified and fixed in newer versions, I'm not happy with firefox and will use other browsers..

Until a few days ago, my Firefox would save all the tabs from the previous session. But now it does not, and I still have all the necessary settings enabled. I noticed that it will save the previous session IF I use the Firefox "EXIT" from the "File" menu. However if I use close the session using the upper right hand corner Windows close box (where the "X"), it does NOT save the tabs from the session. I also notice that when I close the Firefox window using the Windows close box, that Firefox (several) show still running under the Windows Task manager, but not when I use the "File:Exit". Running the current FIrefox version 127.0 (64-bit) under Windows 11.

Nightly updated this morning and the help menu from the sandwich has stopped working. The menu options display, but none of them function. Mouse click makes the menu disappear as if it's going to show the panel attached to the option.

I've hit a crazy problem:

I open firefox and browse to a website. Close Firefox and then reopen and attempt any website and it just hangs. Close the browser and look at task manager and it's still listed - end task open again still no connection to anything. Have tried the Read Only thing in %APPDATA%\Mozilla\Firefox\Profiles\ after a restart of the PC and it stays Read-Only even when I change it. Have tried a new profile which just moves the same behaviour to a new profile ie create a new profile open the browser go to any website, close the browser and reopen and get nothing. I have repaired, uninstalled, reinstalled and I just can't get it to work unless I restart the PC everytime i want to go to a webpage! Anticipate switching to Google Chrome soon if I can't find a solution which is a shame as I have been a Mozy fan for years. Any suggestions?

I would just like to know why it crashes immediately every time i try to run it, my network isn't blocking it and i still cant run it even after turning off anti virus protection

I have been reading the NYTimes on Firefox for a long time, but it appears that I got logged out without knowing it. I could not log back in even though I used the correct email address and changed my password twice. I can log in on other browsers using my latest password. I called the Times and the person with whom I spoke, after trying to get me logged in, finally said that this is a known problem with Firefox. He did not have any idea about the cause or what I could do; he simply told me to use another browser. I use Firefox for almost everything and this is, to say the least, an inconvenience--for instance, if the Times sends me a link to an article by Thunderbird (which is my email program), I can't read the article but have to find it on another browser. Are you aware of this problem? Do you have any suggestions for how I might log in despite it? Do you know the cause of the problem and whether Mozilla is trying to fix it?

Hello! A year or two ago I ran into a problem. While Firefox is checking for an update, it does not load any sites. I have to wait about 5 minutes each time before I can start using the browser. It is incredibly annoying. Has anyone encountered this kind of problem?

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Recently installed a "cleaner" app called PrivaZer. Ran the app and rebooted as part of the process which also included creating a restore point. Once system rebooted and logged in, pinned tabs were gone?! Using the created restore point did NOT restore the pinned tabs. Is there a way to recover the pinned tabs? Thanks in advance. FRANK

Windows restarted to update and all my 100s of tabs are lost (setting me back days of work!)... Firefox is set to always reopen previous tabs, but it didn't work. Recently closed tabs/windows are blank. The Restore Session page - about:sessionrestore - doesn't restore and lists no previous windows/tabs. I went into my sessionstore-backups folder and grabbed a previous.jsonlz4 that has some data but am not sure what to do with it.

Please help! This is a devastating loss of information, as I use my tabs as a to-do list and had many in-progress projects with resources that I cannot all recover just through history.

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

session is completely gone. I tried to restore it via various help articles and forum posts but without success.

I see a stg-backups-ff-126.0.1 fodler in my download folder which contains information about tabs that I had open. But I don't know how to use firefox to use that file.

I alos tried to the \sessionstore-backups folder with files named like "previous.jsonlz4" but I do not get the menu option for restoring a session.

Hi,

I use ClassicPress (fork of WordPress) and I have a problem when requesting a password reset link for it.

When opening the email received to reset password in the firefox dev edition browser and click the reset link I receive an error stating that the link is invalid.

I discovered by trial and error that copying the same link and pasting it manually in a new tab of the same firefox dev edition browser solves the issue because then the link is recognised as valid.

This happened after the update I received last week.

I am a linux mint user if that helps in tracking down the issue.

If I open a second tab on the screen it says the connection has crashed and keeps doing it if you try again. If you reset it resets Firefox including the other tab.
