Power went off yesterday for 30 seconds. Firefox no longer works in safe mode or any other mode. Spent last 3 hours trying every solution I could find to no avail.

Practically every solution offered by Mozilla tells you how to use the software itself to reset it. FIREFOX WON'T START !!! I can't click ABOUT:anything to see what is going on. I can't start safe mode - NOTHING.

Thousands of posts going back 7 years - SEVEN YEARS - show Mozilla has utterly failed to address this issue or even offer a solution when it happens.

At this point I am just trying to get back several hundred bookmarks stored there. How do I do that?

Well, the first thing is when I logged back in from a restart, firefox wouldn't open. It would just say "firefox quit unexpectedly" over and over again and I restarted over and over again. I used AppCleaner to delete (not permanently) the old Firefox then downloaded Firefox from another browser (which I'm writing from right now, Opera) but even though it worked, the links in bookmarks had no logo, my add-ons weren't in the right order, and none of my preferences were saved. What should I do?

Hi, Please help, I can not open this link https://www.canada.ca/content/dam/ircc/documents/pdf/english/kits/forms/imm0006e-2020-10-09.pdf It says I need Adobe reader 8 or higher. I have the correct Adobe installed and document still wont open. I am also getting this message 'user-select' is not supported by Edge, Firefox < 69, Firefox Android, Opera, Safari, iOS Safari. Add '-webkit-user-select' to support Firefox 49+, Firefox Android 49+, Opera 15+, Safari 3+, iOS Safari 3+. Add '-ms-user-select' to support Edge 12+. and .c0169 {

   user-select: none;

} REQUEST chrome-extension://mhjfbmdgcfjbbpaeojofohoefgiehjai/edge_pdf/index.html Computer experts, what does this mean? Where do I go and how do I fix this? This is an extremely important document that is very popular right now. PLEASE HELP

There's a glitch where the little gray box with "Timed Out" appears at the bottom of the browser, but if you hover the cursor over it, it will move the right and if you move to the right and hover it, it will revert.

When logged in to my Virginmedia account,Firefox gives the message"Firefox has prevented this page from automaticaly loading"when I try to view a different page.When I select "Allow"nothing happens.Has anyone else had this problem?

hi, whoever reads this. I've noticed a problem recently in some websites where certain elements (e.g. logos and icons) completely disappear and get replaced by strings of text, which I'm assuming is the code that is used to create them. Usually, it's just one icon, typically a search or menu icon, but there have been more drastic cases, such as the screenshot of the Encyclopaedia Britannica website that I attached. Notice that many buttons, while still functional, are covered with strange text. One thing I'm suspecting is that I intentionally or inadvertently disabled an element (or something of that sort, sorry for my ignorance in the specificities) ages ago that was supposed to make these work, but I don't remember what I disabled, if I ever did. But other than that, I have no clue what causes this. In Tor, where I don't have an account and never interfered with the setup or settings, everything seems to work just fine; the buttons are right there. Hope someone can be of help.

Every time I close Firefox windows, I'm logged out of all websites I had been logged in to. This doesn't happen automatically at a certain point in time, it only happens when I close all windows. I already tried the about:config thing that was in the solution for another person who had a similar problem, but it didn't work. This has been going on for about a month or two now.

The other day, my browser updated to version 87.0, and ever since, I've been noticing black boxes appearing on various tabs. They go away if I scroll up or down the page they're on, or if I click on to another tab then back to the one I want. These boxes also appear over the tabs themselves at the top of the browser page.

Has anyone else noticed these? Will there be a fix for them in the near future - sooner rather than later?

Any help would be appreciated.

After the latest update, the PDF Preview function has broken. The screenshot attached shows the new view I get after the update. I cannot resize the preview window using the corner visual control thingy (that's a technical term).

This worked as of 2021-03-27 and upon restarting my machine today 2021-03-28 a new version of Firefox was installed and now this error has occurred.

Is there a way to roll back the version until this bug is fixed? Or does anyone have any ideas on how to fix the issue?

Things I have tried: Restarting the browser and computer clearing cache and history I have not disabled extensions, but the only extensions I use are Ublock Origin, and a couple other high profile extensions that should work with any progressive update.

Thanks,

Daniel

So I've been experiencing a rather annoying bug/issue, and I have a work around for it, but I would love if anyone could help me figure out the issue at hand. I couldn't find a relevant, up to date solution for this issue.

Basically, certain websites (the most notable being Reddit) will eventually no longer load. In fact, it won't even try to load. I will click a link from a Google search, or even just type in the URL for Reddit directly, and Firefox just does nothing. No error, no loading, nothing. The tab will stay blank with the URL listed as the name of the tab. I can't seem to tell if other browsers have this issue as it requires a bit of use/time to pass, but it doesn't seem to be an issue in Explorer. It isn't JUST Reddit, but it's only a couple of sites that this occurs on.

I do have a workaround --- if I tell Firefox to "Forget This Website" - suddenly it will work again. I will be logged out and see the default page due to having deleted all saved dated - but the site will work (for maybe a day) before I have to forget it again.

If this was a once a month type issue it wouldn't be a big deal, but the fact that I have to constantly re-do my local settings because of this is frustrating.

I am running Windows 10 and my Firefox version is 85.0 (64-bit). I have tried disabling any add-ons such as my AdBlocker, however that does not fix the issue.

Firefox fails to recognize my GPU's and uses my integrated GPU rather than my dedicated GPU. I'm using Kali Linux (usually alike Debian Sid on repository grounds), I'm invoking it using DRI_PRIME=1 environment variable because that's where my Radeon RX560 is but firefox opens with this warning on terminal:

[GFX1-]: More than 1 GPU from same vendor detected via PCI, cannot deduce device.

I've even tried nightly but it doesn't recognize the dedicated GPU either, my other GPU is a Radeon Vega 8. All other other programs on the system and even Chrome recognize my RX560. Using DRI_PRIME=4 (that's where my Vega 8 is located) launches the browser with the same warning and again uses the integrated GPU, I know which one is using because radeontop shows memory usage only on the integrated GPU.

I don't know if this isn't the right place to post this, if you know a better place please tell me. Thank you in advance.

Hi,

My firefox has been crashing/quitting randomly few times in a day even in safemode. I was not able to find solution.

Kindly advise.

Thanks

Every excel document I open via Sharepoint on my firefox browser, crashes/freezes, making me unable to work in and I have to force close that tab, as even reloading does not fix the issue. This happens so fast, that when opening an excel via link, I don't even have time to choose the option 'Open in App'. I have already 'cleaned' my firefox, but the issue has not disappeared.

Ok so recently I made a post about the issue of Firefox crashing and having to reinstall it, then kind of fixing it by moving my old profile into this one. Thing is, Firefox crashed on me. Again. And now my profile is yet again, deleted. I tried doing the same thing I did but it didn't work. But there's actually two Firefox folders, one that refuses to leave my desktop (I was actually planning on asking for help on this one) and one that I put in the Application Support place. None of it is working though. It could just be because my computer has some issues though, (it's an old one, 2-4 years old and the sides are a bit damaged because somebody forced it into a tiny box and sent it back and I've also dropped it a few times, although I don't think that would impact it, and also Firefox crashes every so often when I open my bookmarks) this isn't the first time Firefox has crashed, only the first time it crashed and erased my profile. If it helps, I was clicking on my add-ons to get a tomato timer to go (after reinstalling it because some of my add-ons didn't work) and then it crashed, with the twirly rainbow circle. I force quit the app and came back. Voila. If anybody has any help, please do. I have work to do and I don't fancy doing it with this hanging over my head.

Firefox automatically update this morning (2021-3-27) and at least one month history was erased. I always reopen the last session (it was 2 windows and a lot of tabs yesterday) and I just get a very old session. My history panel has nothing for March, just February !

I don't understand ! And it's very unpleasant because all my work-in-progress (my researches) disappears ! Does somebody have an explanation ?

Thank you very much

Starting on Sunday 3/21, pasting an image into a gmail message in Windows 10 from Firefox 86.0.1 double pastes it. Two images, not one. Pasting text results in a single paste, as would be expected. What's wrong with image pasting?

Appears to only happen in Firefox. Tried with Edge and composition worked fine.

I found that high-lighting an Image -- (NOTE: "jpg" -- ====> NOT ".png") and then COPY, followed by a PASTE into Gmail produces the correct ONE image.-

However, if the Image is ".png", and I move cursor OVER the Image, then Right-Click, select COPY Image and then go to Gmail and issue either a CTRL+V or PASTE, I get 2 images.

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL

I posted this earlier today and can't seem to get back to where it is shown. The above code is what I woke up to on Firefox. Subsequently, I reinstalled a second edition of the browser and it works fine with the exception that I can't install Dashlane on the second version. When I attempt to install Dashlane, the previous version of Firefox opens and wants to install Dashlane itself which, of course, is useless as that version is where I get "Error code: SEC_ERROR_BAD_SIGNATURE" continuously. My question is, how do I get rid of the offending version of the browser?

Turned on my imac this morning and the Firefox browser gave a "Error code: SEC_ERROR_BAD_SIGNATURE" for every page I tried to open. I have reinstalled the browser and that one is working properly. However, when I try to add Dashlane to it, the old browser opens and the same error message is displayed making it impossible to use Dashlane on the newer version of the browser. How can I get rid of the version that opens up when I try to install Dashlane on the working browser?
