Suddenly almost everytime I load a YouTube video I have to watch 2 - 4 min of ads, sometimes two in a row before the video starts. I no longer have the skip ad button. If I load the same link in Chrome or Edge I don't have this problem. My search engine is Duck Duck Go, but if I go to Google first and then to the video I still have the problem. I also have the Maleware Bytes ad blocker installed. Any suggestions?

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

Hello,

I experience constant tab crashes a couple of days now. I tried safe-mode and re-installing the browser. But the crashes still persists. This only happens with firefox.

Been trying to identify the problem. Here are some crash reports. All of them have the signature (unloaded T_Prevent64.dll)

Firefox on Windows 10 desk top suddenly stopped working with error message

XUL Runner Error. platform version 127.0.1 not compatible with Min version >= 127.0 Max version <=127.0

N.B. This is another machine - not this lap top

Please advise

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..

Hi, I often have multiple Firefox windows: 2-3 windows fully expanded, the rest minimised down in the right hand side of my Dock on my MacBook Air.

This makes finding a particular web page difficult among the minimised windows. If I hover over each minimised window only a description of the most currently visited webpage is displayed.

But if I had a way to label the entire window, and I grouped similar webpages together each a window, then at least I could go straight to one particular window to search for the webpage, rather than have to go through all of them.

Can someone explain how to do this, pointing me exactly to where the button that needs to be pressed etc is?

Thanks.

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Similar to the issue described in this thread (https://support.mozilla.org/bm/questions/1240674), I am unable to open Firefox - it simply refuses to open. I've tried multiple times, the option key, and re-installing. Nothing seems to work, which suggests something about my user settings is the issue, but a) I am not keen on deleting this if possible and b) I won't delete my user settings unless that is necessary. Like the attached thread, I am happy to attach crash reports, but without the ability to even open Firefox properly it's not obvious how I do this - force-quitting it just sends a report to Apple.

Any help much appreciated - I'd quite like Firefox working again.

My laptop is a MacBook Pro 13 2020 (Intel) running macOS Monterey (12.7.4). I installed the version of Firefox available for download as of writing (v127.0 based on Finder).

HI for the past four days I have been getting the following error message when attempting to load www.canberratimes.com.au

"Application error: a client-side exception has occurred (see the browser console for more information"

This is happening on my Windows PC only. I can access the site on my Firefox browser on IOS.

I am running the most recent version of Firefox 102.0.1 (64 bit).

This is the only site displaying this message.

Grateful for any assistance in resolving this.

Kind Regards, Peter

Hello. I have a problem with turning off google safesearch. I'm 28 years old so it's not a problem with google acc. I have same firefox on pc and on laptop. On pc and on smarthphone it's easily turning off and if i'm using edge or chrome on laptop it's also turned off, but if i'm using firefox exactly on google it's always turned on no matter what i'm do. Just in case, if i'm using for example bing search in firefox it's also turned off, likely it's always turned when i'm using google with combination in firefox. Methods that I already tried: 1) Turned off in computer settings (not worked) 2) Reinstalled browser (not worked) 3) Checked in my wifi settings (not worked) 4) Updated everything (not worked) Waiting for your help.

This is the site https://one.walmart.com/content/usone/en_us/company.html this site I connect to for work related issues, I can use private browsing, but not the regular browsing.

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

When I open Firefox I get a message telling me "Failed to read configuration file. Please contact system administrator". When I click OK Firefox opens normally and seems to be fine. Not sure what is going on here. Any ideas why this is happening and how to get rid of it?

Windows 10 64-bit Firefox 115.3.1 64-bit

Any assistance will be greatly appreciated. Thanks

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

Hello there; I had installed the "savefrom.net" extension. This extension automatically generated the website address to the "bookmarks toolbar". I deleted the extension and deleted the shortcut as well. But when the bookmarked website shortcut "firefox" is closed and reopened, it adds itself to the bookmarks toolbar again. No matter what I did, it didn't work. I don't want to delete Firefox completely and reinstall it. Because there are too many shortcuts and data that I use all the time. How do you think I can solve this problem?
