Firefox Support Forum

Trying to open Firefox in Windows 10 is suddenly only showing a completely white screen (no title bar, closing X, etc) and can only be closed by right clicking on the start bar icon and selecting "Close Program"

Have tried everything to fix the problem so decided that I would have to use the Control Panel and completely remove/uninstall the program and then re-download and install new (was able to save the bookmarks in html format from the "c" drive.

When selecting the Uninstall option in the Control Panel, rather than uninstalling as with any other program, a dialogue box appears offering to repair/reinstall the program, but on clicking the accept option another dialogue box appears stating that Firefox must be closed first --- but it is closed and also proved to be closed through the Task Manager section.

The Firefox version is 100.0.2

How can I completely uninstall Firefox when no option will allow this to happen. I have even tried via the "CMD" command.

Any assistance will be greatly appreciated as I have been working on t his problem for three days without any success.

Hello. I don't know which Firefox release broke this essential feature. The problem started after I enabled Aero in my Windows 7 system. It happens often if I have an open tab with https://www.o2tv.cz/ which uses some DRM to play TV content.

Previously, with older versions of Firefox, clicking on a wave file would open the wave file in the windows application that is registered for opening wave files. This was also the behavior with other audio files.

Now, it only offers to download the file which is incorrect behavior, the file just is needed for now and after now has passed, there is not reason to keep the file on the computer.

How do I restore the proper behavior.

Firefox crashes randomly with no crash report being generated. It seems to have started doing this about a month ago. Nothing in particular seems to trigger it, and all of my software is up to date. It just closes any and all tabs that are open, as if I exited out of the program entirely.

Occasionally, the internet will stop working for my “default-release” profile. When I search for something or go to a website, I get “Hmm. We’re having trouble finding that site.” (refer to the attached screenshot). Then, I have to wait a couple of minutes and reopen Firefox to get back internet access. But, other profiles work uninterrupted, and other applications also work fine. I don’t have any antivirus installed. I tried reinstalling Firefox to no avail. It would be really helpful to hear any suggestions or solutions for this problem.

Firefox will hang sometimes when loading some pages on the recent release version!

It will hang forever and only thing can do is to use task manager to remove it!

After that, if you load this page, this issue still happened!

The only thing can do is to uninstall firefox!

For example this page : https://tw.news.yahoo.com/%E7%9B%B4%E6%92%AD%EF%BC%8F%E7%A2%BA%E8%A8%BA%E6%95%B8%E9%99%8D%E7%96%AB%E6%83%85%E9%AB%98%E5%B3%B0%E5%B7%B2%E9%81%8E%EF%BC%9F%E9%99%B3%E6%99%82%E4%B8%AD%E4%B8%8B%E5%8D%88-2-%E6%99%82%E8%AA%AA%E6%98%8E-022552183.html

Certain sites (the latest being https://azgaar.github.io/Fantasy-Map-Generator/, which i've downloaded successfully from before) cannot be downloaded from - firefox gives the error of "[site] attempted to automatically download multiple files. The site could be broken or trying to store spam files on your device."

I know these downloads aren't spam or malicious, but when I hit the "Allow" button to give permission, there's no change. The downloads remain blocked and new downloads are blocked.

I've turned off my antivirus shields to see if that was causing it, but to no results.

I sincerely thank you for your time and know that you're quite busy, and look forward to hearing back about this issue.

Posting on behalf of a user who hit the VPN inbound queue with a question better suited for this forum:

The tab bar, toolbar, and address bar placement in my Firefox Desktop browser has recently changed. I have been trying to revert these recent changes as they interrupt my current workflows.

I DO know which prior profile save contains the desired info however, it contains many files and I DO NOT KNOW which files I need for the bars to be restored. If you could provide me the name(s) of the file(s) that holds the bars data, I am probably saved, hopefully saved.

As of two to three days ago (ca 20/05/22) when navigating to a website (regardless of whether it has been previously visited or not) a message appears stating "PK not found (e1)". I have to click it in order to view the website. Sometimes the message also has a checkbox stating "Allow notifications like this from www.example.com to take you to their tab". I am using the latest FFox 100.0.2 and am fairly sure the problem started after the update before the last one (the last one was this morning 22/05/22).

This has happened to me on 3 different computers.

Today, I installed Modicia linux operating system on a new computer. Then, I installed Firefox browser. I logged into Firefox the normal way and all my book marks and passwords etc... were imported into the browser, but when I clicked the "Home" button, my customized home page was gone. There were just a couple buttons pre-configured to whatever the default thing is showing twitter and 2 or 3 other buttons, but not what I had spent 3 hours configuring on my other computers. This has only happened on a new install of Firefox.

When I went back to my old computer and started Firefox, they were all gone!!! All of them. How do I get them back without programming each individual button all over again? The picture shows what it looks like NOW. Before installing Firefox on this new computer, all 32 buttons on my home page were individually configured with URLs and custom icons. Walt

I used to be able to get on Amazon with no problems using Firefox. Lately, the website is all chopped up. Blue words with underlining appears on the pages. I can view Amazon just fine under Safari.

Hello, I'm using Firefox 100.0.2 (OS: Ubuntu 20.04). It is not possible to manage if/when firefox updates are installed. In the options-section, there are some information about the current version number, however no chance to configure anything update-related. Updates just happens automatically and interrupt current sessions, leading to spontaneous (and surprising) dysfunction of the opened browser. That's very annoying in case of video conferencing, for example, because it is not possible to open any new tab or windows, always the note there "you have to restart firefox now" - in practice, just like a crashing error. And, the suggested restart does not re-open the current opened tabs/URLs!

Furthermore, within some updates, my language settings get lost, so it turns to English language automatically and I always must add my language packet manually again and again. Thats really annoying and maybe completely disruptive for people that are not able to read in English!

Is there any chance to come over this? Otherwise I guess I must leave using firefox as browser, however this would be not the aim I actually follow. Thx!

Suddenly anytime I use youtube or gmail it loads very slow. I have tried flushing dns, reinstalling firefox but no matter what it just hangs and doesn't load. For example I'll click on a youtube video and it will say I'm offline or on gmail if I try to compose an email it says to retry because it breaks.

I refreshed Firefox and all my passwords disapeared even though it stated they would be saved. I followed online instructions and copied and pasted the old data into the new profile. Although I can see the old login data is there nothing shows up in the saved passwords section in settings. HELP! all my passwords are badly required as I have no other record.
