Firefox Support Forum

My Firefox installation (86.0 64-bit on macOS 10.15.7) always crashes on opening gmail.com. It seems to be on the point it loads the hangout stuff, but that's subjective. Also seems to happen on other google domains, like meet.google.com

Some Crash ID's bp-b0a5daca-f85f-47dc-a306-647250210306 (gmail.com crash) bp-d4e0a614-cea4-41b3-b665-e5abd0210306 (meet.google.com crash)

What I've done:

• Tested if crash happens in safe mode (yes)
• Refreshed my installation: still happens
• Removed all cookies for google domains, still happens
• Created a fully new profile, crash still happens
• Installed a new Firefox from the website, crash still happens

As the title says, this has been an issue for a while, and I'm just getting around to posting about it. I figured I would help out and make the issue known.

If you are in Gmail, using FireFox, and you click the paper clip icon to add an attachment to your email, while you are browsing through the window to select your attachment, if you press space-bar to preview the attachment (before you click add, while you're still browsing) and then you use the arrow keys to cycle through the list of items to preview whatever is next in the folder, FireFox will crash, without fail every-time.

It's frustrating because usually when I'm attaching some images to an email I like to preview them before I attach them to make sure they are the correct one, and when I use the arrow keys to cycle through the previews, FireFox crashes.

Just thought I'd make this known! :)

Hi Firefox keeps on suspending when switching between different tabs (already opened or new tabs). When the FF is hang I can do nothing in the FF, but I can operate on the Windows (8.1) without issues.

I have already tried: - Put new Firefox portable - the same issue - Close other tabs - Disable EMET for Firefox - Prevent accessibility services from accessing your browser set to True - Security.sandbox.content.level set to 2 - Disable add-ons plugins and start in safe mode

Nothing of above helps. I would appreciate If you could provide the solution. I attached Troubleshooting information.

Hi, I'm an eng trying to do cross-browser debugging. Firefox is giving me a weird bug. To start:

- No plugins installed - No ad blockers installed - Cleared cache, cookies, history, everything - version 58.0.2 (64-bit) on Mac OS 10.12.6

Having trouble repro'ing this bug but here's my best shot.

Navigate to https://www.joinhonor.com/care-network

Shrink the browser width to about 500px.

Scroll a bit, wait a bit. Maybe do something else for a few seconds.

Page goes blank except for header, footer and maybe a few other components.

Doesn't happen in Chrome or Safari.

I've been able to repro on a few pages but not consistently.

Any ideas? Thanks!

Hi everybody, do you know why in Firefox stable 60.0 the 'Take a Screenshot' context menu icon is missing its icon? It look unbalanced and a little bit unprofessional.

In the past weeks, suddenly my Firefox started behaving really weird - a few times a day the currently opened tab becomes unresponsive (you can't click or hover anything) but you can still scroll through them (at least a bit - after that point, it's just plain white). At these times, the cursor is the hand one, during the whole unresponsiveness episode, as if everything was clickable (though obviously clicking does nothing). You also can't close the tab during this tab - the only way is either to wait a good 30 seconds for it to unfreeze or to change to a different tab and close the unresponsive one. When you do change tabs, though, the newly opened tab sometimes disappears completely, with a radial loading circle appearing in the middle of the screen for a few seconds before it magically reappears (it does _not_ reload, though!). From what I've been able to observe, this tends to appear on content-heavy websites like Reddit, Facebook and YouTube most often.

What is happening? I haven't changed my browsing habits in the past weeks, nor have I installed any new add-ons. I've tried disabling the ones I have but it's still happening with them turned off. What else may I try?

In Firefox 60 when I go to delete individual cookies I can no longer use the "delete" key on the keyboard. This was always useful for quickly deleting any unwanted cookies, scroll using the arrow then delete. Now I have to ctrl+click, scroll and click remove. One mis-click and they all get unselected and you have to start again. How to re-enable the delete key?

I think I found an error using which I can pass through a user account. You have entered the options for entering a second email in your settings. Now you can enter the second e-mail without confirming the password. Then you can set it as the main e-mail. Then you can change the password with the help of the newly entered e-mail!

This way you can change your account in a few seconds :(

Hi. Firefox keeps crashing when I try to download a file, since update version 59.0.2. I'm using windows 10 64 bit. If I restart the PC It runs fine for a while, but if I put the computer to sleep and use firefox after waking it up. Browsing is fine, but if I try to save an image or download a file it crashes. The file gets saved to the download location, but if I start firefox again. The download starts over, deleting the previously downloaded file.

I have a sizeable number of bookmarks saved in desktop Firefox. They're all saved in the bookmark toolbar. To save space there, I keep many of them nameless so the bookmark is only identifiable by its favicon.

When I downloaded the Firefox app on my Galaxy S8 and set up Sync, it brought over the bookmarks with names onto my phone. However, not only did it not sync my nameless bookmarks, it just deleted them outright. I no longer had my favicons in my bookmark toolbar on my PC.

I found out how to restore my bookmarks, but is there a way to get the nameless bookmarks to sync over to my phone as well? Or at least stop Sync from deleting them? Is this a bug of Sync?

Thanks!

We use an internal email server which is accessed via Firefox (MDaemon) and when pasting a screen capture (either via printscreen or GreenShot) in to an email, the image pastes twice.

This is only the case within Firefox, not an issue when using Edge.

It is occurring company wide so I doubt that it is a profile issue. I have tried running Firefox with hardware acceleration disabled but it didn't have any effect. I have also tried starting Firefox in Safe Mode but again, no difference.

Example shown below; paint window which was captured using alt+printscreen

Does anyone have any suggestions as to what to try next?

I am considering switching from chrome to firefox. While trying to import my passwords i wont get them all.

Using the import feature inside Firefox I will get about 70% of my usernames and passwords from chrome.

Why it wont import the rest makes absolutely no sense at all.

Firefox gives no option to import from a CSV or anything else but that one button.

I get the impression the whole feature is not tested properly, If Firefox wants people to switch browser this just has to work flawlessly.

Hi,

I am photosensitive, and encounter a lot of safety and accessibility problems online. I have configured Firefox to try to block as many strobes and other dangers as possible, but I am not an expert, I haven't found enough solutions, and USERS SHOULDN'T HAVE TO BE EXPERTS TO USE THE WEB WITHOUT MIGRAINES AND/OR SEIZURES.

I have posted a bug about one of these problems. It was "resolved invalid" because I should report an "accessibility bug," instead of reporting an accessibility bug.

https://bugzilla.mozilla.org/show_bug.cgi?id=1472345\

I know there'sa an underlying refusal to make it possible to use the web without injury, because:

https://bugzilla.mozilla.org/show_bug.cgi?id=227886 is still WONTFIX

If there were a safe browser, I'd use it, but there isn't.

Hello, the bug

https://bugzilla.mozilla.org/show_bug.cgi?id=1394851

was described as solved, but the issue is present in my version of FF (see above).

I have browser.download.useDownloadDir;false

but the screenshot extension continues to save in the default download directory.

thanks and best wishes Chris

Hello! Every time i wan´t to delete digital signature nothing happens. After firefox restart digital signature is still there. After comp restart digital signature is still there. I did deleting several times and nothing. Then after time it is deleted. So I think you have a severe security issue here.

With Firefox version 63, I have the problem on YouTube and Netflix, if I snap Firefox in a corner (with mouse or WIN + arrow keys) and switch a video to full screen, left and right is still a few pixels square. In addition, the taskbar is in the foreground (can not be fixed). [IMAGE 1]

If not left, right (top or bottom) snapped then it works, if Firefox is maximized too. The error occurs only in Firefox. Exit Explorer.exe and reboot PC does not work. Error exists since update on the first day of release (early October) - version has been withdrawn by MS,

I also installed the version on my laptop and have been updating ever since.

Apparently the error also occurs with some others: https://www.reddit.com/r/Windows10/comments/9lwzmm/fullscreen_broken_in_october_update/ but it has probably not changed.

Useful data: Windows version 1809 build 17763.134 Graphics driver up to date Firefox completely reinstalled (profile, cache & cookies deleted) even without add-ons started. 2 monitors On the laptop (also tested with 2 monitors) no problems.

I am thankful for every help. Error is really annoying.

Yesterday all files and folders on my (win10) desktop suddenly got two blue arrows on them. I googled the problem and it turned out that the desktop folder had gotten the setting for compressing all its content turned on. I changed it back to no compression and the arrows disappeared. Today it happened again, and I changed it back again. However, I noticed that all newly downloaded files are still getting compressed. I made a new folder for the downloads (previously the went straight to the desktop), and the files I copied in to it are fine but all new downloads from FF still get compressed. When I download from Chrome it's fine.

Is this a Firefox problem? I looked through the settings but can't find anything relating to compression.
