Firefox Support Forum

I've been having frequent trouble starting Firefox for the past month or so.

Sometimes I get the Windows error message that Firefox crashed and asks me to restart, check for problems, or debug the application.

Sometimes Firefox will open on a "New Tab" and fail to load my default home page (http://localhost/default.html). A dot on the left side of the tab cycles back and forth continually.

I'm using Windows 7 Home Edition with IIS installed.

Thank you.

Hi,

this is a weird issue with "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0": The contents of Dokuwiki codeblocks disappears when clicking in the block, not only on self-created pages, but also here: https://www.dokuwiki.org/plugin:code2

The problem exists only with code blocks in the lower half of larger Dokuwiki pages, therefor might be a memory/cache issue.

Reproducible as follows: - on different machines with FF 68 - 78. - in Safe Mode - with a new empty FF profile

Cannot be reproduced with other browsers (Chrome).

I am quite cueless so far. Any help appreciated.

Not sure when this started or why it is happening. I have double checked that my settings have Google search set as my default search engine. Instead, Yahoo Search keeps popping up.

How can I stop this?

Thank you!

When I save a pdf-file it is automatically converted into a firefox html dokument. Also all my old safed pdf-files are converted. What does happen? And how can I stop it? I'm not able to safe my scans as pdf anymore.

Basically since about 15-30 days ago my firefox has been constantly crashing when I open new tab or even simply a link to a website... the more 'power consuming' process is the more likely it will crash. Simply browsing stuff has nearly 0 likelihood of crashing. The frequency varies - something like youtube or steam game browsing will crash with extremely high frequency and will work fine after reopened. Some text based websites will barely ever crash the firefox.

What happens is either instant crash(most frequently) or infinite 'not responding' with the solution being task manager end process.

Either way it happens - reopening browser reopens all tabs that were open.

What I tried: 1) Cleared cache 2) Disabled all extensions. 3) Tried checking about:crashes - 0 reports there in last 30 days... meaning whenever I crash no actual crash report comes in.

I am using chrome at the same time and it has 0 crashing issues under similar circumstances.

Hi.

Can someone please tell me why my personal network site - https://www.myanimatorssketchclub.com

- is suddenly not loading on my Firefox browser? It is hosted by Mighty Networks. 

I have not had trouble with it before - for months - and none of my other regularly used sites fail to load. I note too that the same network site loads with no problems on other browser. Even refreshing, restarting or opening in 'Safe Mode" on Firefox does not change things.

I have attached a screen capture to show what I see.

I hope this can be fixed as using Firefox is really important to me and I don't want to have to move to another browser if this proves a permanent thing.

Thanks for your help!

I clicked on refresh and all my addons and logins are gone.

refresh does not sound like a destructive operation

im about to activate the profile again through the backup so its ok for me but you should consider for average people to rename it

Every time i open my firefox browser i got this searchmarqis or searchbaron set as my default search engine and i am not able to remove it paermanenetly even after repeatedly deleting it from search engine setting.How to get rid of this bug?

Just installed Win 10 Pro on a new machine, and as the subject line says, the ebay webpage shows up as text only in Mozilla. Works fine/as expected in Chrome. I've opened Mozilla in safe mode, purged the cache, adjusted font size. No joy.

I was playing a browser based game and it popped up with the error saying:

an error occured running the unity content on this page. See your Javascript console for more info. The error was: InvalidStateError. A mutation operation was attempted on a database that did not allow mutations.

uh... what? I have no idea what Unity is or does. I have no idea (even looking here), how to open Javascript console, and I simply loaded the page. How did a mutation operation, whatever that is, occur?

Anyone have any idea what that means or how to fix it? If so, I'd appreciate any help.

I've been using Firefox Developer version for some time now on Mac OS and have never had a problem like this before.

However, since version 80, Firefox Developer fails to render the new css after a change and save has been made to the style sheet even after multiple browser refreshes. Caching on the server end has been disabled so I'm really trying to find a solution to this issue as it has forced me to find alternative browsers to develop with like Safari since Firefox Developer has become unusable for me.

I've gone through and performed manual cache flushes on the browser from the settings/preferences panel. On occasion, by quitting Firefox Developer edition and relaunching it will then render the new changes but only after a quit and relaunch and sometimes using a private window as well. This is happening with multiple hosting services so it's not any particular provider.

This is most annoying. I've even reset Firefox Developer a number of times to default settings without any extensions etc. and still the problem exists.

Earlier version of Firefox Developer don't seem to be exhibiting this problem. I'm not running any proxy's or special configurations with the settings either.

Any assistance to finding a workaround would be greatly appreciated or I'm going to have to stop using Firefox Developer version altogether.

Thank you,

Every time when I upload a file to a website, as soon as i click Browse to find the file, Firefox crashes/froze on OS X. When I use Chrome to do the same thing works fine. Have entered "about:crashes" on Firefox address bar, have several unreported IDs. Unable to submit the IDs, shown failed when clicked.

My internet connection is ok, when I load my home pages also ok but when I try to load a website it takes forever

For example If I try to log into my gmail account it will not load, the same with other sites

I hsave tried using EDGE any they load ok so I take it its a FF problem and not my laptop

help appreciated

Hello. I ve got a big problem on my Firefox browser. When im using other browsers i dont have this problem, it s only on Firefox, but i love using Firefox and i want to fix it.

Problem which i have shows up on youtube and sometimes on twitch. When im watching youtube video in vp09 format there are absolutely no problems with frames but when a video is in avc1 format - boom i cant watch it because of super frame drops - like a 90% of total frames are dropeed.

Example video: https://www.youtube.com/watch?v=xr-zCc9VUto

My pc is not the best but not the worst, i dont think its hardware problem because as i said, on other browser i dont have this problem watching the same video it isnt dropping frames. CPU: Xeon X5450 GPU: GTX 660Ti RAM: 8GB

This problem is with me since about a year, i dont know when it happened. Please help me, how to fix it?

firefox mark every website as insecure when http2 is enabled in about:config if http2 is disabled, everything is fine. its happen since long time ago. i think its kind of bug so i did not upgrade it till now. and still exists. -

My Firefox just crashed. The usual box appeared to say that it had crashed and it will restart and recover the tabs I had opened.

Unfortunately, it appears to have started completely afresh. No recovered tabs, no extensions, no bookmarks, absolutely nothing.

After reinstalling a couple of extensions, I signed into my Firefox account expecting my bookmarks to be restored but nothing. It's like everything had just been wiped with no warning whatsoever.

I am now at a loss. Everything has gone. Is there any way of restoring my bookmarks? Is there a temp folder of some sort on my system that I may use to recover them?

Thanks very much and hope you can help.

I clicked an .exe to download a zoom meeting list. It installed malware. I'm unable to go to add-on's, options, etc - it opens a blank page. Redirects webpages to all sorts of stuff like porn and IDK what. How do I identify and remove?

What can I provide to assist beyond this: seems the "root" URL is spontaneousguarded.com

Using Chrome, as I do not want to enter my info to ask for help on a compromised Firefox browser. Searching on Chrome doesn't bring anything up that can help an (NON-IT) person. I'm also unable to allow troubleshooting information using Chrome. Thank you!
