Firefox Support Forum

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.

Yesterday on my linux computer I noticed that my container setup ise back to the default setting. Now I'm using my windows laptop, and it is als back to the defaults. I'm afraid the same thing will happen when I start using my windows desktop. Should I poll the network cable and delete my firefox sync data, so I can hopefully save my containers setup? Or is this not going to help, and I'm fucked anyway :)

Dear,

I have been using Firefox Developer Edition for many years without any problem. I sync Firefox on my different PCs, so they are basically all the same in setup. Unfortunately, Firefox now crashes constantly on my main PC. I have therefore temporarily switched to the default FF variant.

Of course I have tried all the steps shown here on the forum but without any result that I can see. Both in safe mode with or without addons. No matter FF crashed.

The error ID: Crash ID: bp-20d91ca4-1f79-4211-a3d5-4fd7c0240507

I hope someone can help me on my way ,

Regards,

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

Dear all, I would like to know how to disable the automatic insertion of the tag
in a text editor in Firefox. I am using Froala, and I am experiencing this only in firefox. Chrome and Edge do not add this tag automatically. Thank you for you support. Kind regards, Cristiano

Hi there, thanks for your attention I'm a web developer and new to using firefox. I was using chrome for years and now just because firefox on android let's us install add-on like it's desktop version I'm switching to firefox. as a developer I need to learn about the features firefox offers to developers or ask for any features that are missing right now, so my current issue is about the pictures I will attach. I want to have more information about the element that I'm inspecting right in the tool-tip over it for example it's active font-family or things like that. It took me sometime to figure out how to find the active font of the target element thanks to This post. but in chrome it's showed in the tool-tip.

Merhaba

My Firefox browser is somehow corrupted with foreign language features. See in the picture that much of the text is in English - the selected and preferred language. It is what the Settings are set to. But notice that bits and pieces are in some other language. I recently made a trip to Spain and used translation features while there - but those was all reset to English. I've gone into Troubleshooting mode; I've restarted; I've reset and restarted. But I can't seem to get rid of the gibberish. WTH!!!! All copies of Firefox, on all owned Mac machines (i-Phone; Mac Mini; I-Mac Pro; I pads) are set to English. About the only thing I haven't done it uninstall and reinstall Firefox. Thanks for any help you can offer.

So this problem keeps happening to me - I click "upload" on a website and nothing happens. For example, trying to upload photos to my website or upload files to a platform. Frustrating. To work around it I've been using a separate tab of Google chrome but it's such a pain to keep swapping back and forth. Please help!!

I cannot open any Games on the NY TImes site with FIrefox for the past month; no problem with Chrome. Today, two article links opened but then the page went blank (repeatedly), while other links worked fine. Again, no problem with Chrome. My wife can't get into proxyvote.com with Firefox--again, a blank screen. Where is this weirdness coming from?

Hi Friends.... This morning logged into my website as usual and this message appeared on the home page. I have not checked the link as it seems potentially malicious ... It does not appear when visiting my site on Safari. I have emptied the cache I have been through troupbleshooting mode I have reinstalled Firefox and it still is there..

How to rid myself of this

All help gratefully received Graham

I'm having trouble using a particular site, that I used to be able to in particular clicking on sub menu's from a context menu if that is the correct term, meaning I cannot click an item/button to reveal a menu below it. From the image supplied there are 2 'menu's' with a < character that when clicked should reveal a sub menu of items, works in Edge/Chrome etc.. the only extension I have is Keeper.

My yahoo homepage on firefox looks totally different than it did last week. Chrome and edge still look like the home page should but firefox does not. I screen shared with yahoo and they said it was a firefox issue. Anyone know how to make the homepage look like chromes and edge? I added pics from edge and firefox for comparison.

Howdy,

Workflow: I have a firefox instance already running. I want to launch a new firefox in safe-mode to test something without disrupting my existing firefox.

Problem: I try to launch a new firefox in safe mode using `firefox --safe-mode`, but firefox just opens a new window NOT in safe mode.

I think it may because firefox in safe-mode requires launching launching from a new instance rather than attaching to existing instance.

`firefox --help` shows a flag I can use:

--new-instance Open new instance, not a new window in running instance. --safe-mode Disables extensions and themes for this session.

So I run `firefox --safe-mode --new-instance`

now I get error popup with message:

"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

Now I think what is the point of the flag "new-instance" if Firefox doesn't support multiple instances?

Regardless, how can I launch firefox in safe-mode without disrupting my existing firefox instance and without relying on creating a profile just for this?

I have enabled Firefox Sync between my laptop and my Android. When I go to the manage history tab on my laptop, the history of both my laptop and phone is shown but without the device the tab was viewed on. Is there a way to filter history based on which device I viewed on?
