Firefox Support Forum

Bonjour, Hello,

I contact you because, even without an adblocker, Youtube is very slow with Firefox navigator. I don't understand why and I don't have this problem with Google Chrome ? Fews years earlier, I never had this problem with slow Youtube when using Firefox Navigator. I don't know if the problem comes from Youtube or Mozilla and I contacted both of them.

Thank you.

Bonjour,

Je vous contacte car, même sans bloqueur de publicité, Youtube est très lent avec le navigateur Firefox. Je ne comprends pas pourquoi et je n'ai pas ce problème avec Google Chrome ? Quelques années plus tôt, je n'avais jamais eu ce problème de lenteur avec Youtube lorsque j'utilisais Firefox Navigator. Je ne sais pas si le problème vient de Youtube ou de Mozilla et je les ai contactés tous les deux.

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

When I open poges now I see often "Firefox darf diese eingebettete Seite nicht öffnen" maybe similar to "Firefox can't open the imbedded page"

I can't see my own music tracks posted on x.com! That's a kind of fraud! What are you doing? At SAP I have to use Edge on Linux already cause you are doing a very bad job! WTF is going on? Are you doing anything or just breaking things?

As the title says, it is very slow with Ublock Origin. I have refreshed Firefox and without Ublock it obviously works but I would like to keep the extension because it is the only one that works with Youtube Ads right now.

I am getting "Secure Connection Failed", Ive seen literally hundereds of same error also exist here. Like most of default solution (which is below) did not work for me. My laptops time is correct, And I highly doubt reddit and most of internet has issue with its security certificates. And other browser works just fine. So What is my solution other than immigrating to new browser?

I would like to force spellcheck for all websites, and override any HTML code from the websites. which may be disabling it. This should be done automatically and not by inspecting and manually altering the HTML. I consulted with ChatGPT and tried adding some code to my existing userChrome.css but it is having no effect, even after clearing cache and restarting Firefox. For instance, faxzero.com has a form with spellcheck disabled. I tinkered with the CSS and kept testing faxzero, but the spellcheck always remains disabled. How can I accomplish my goal?

Code: body[spellcheck="false"], input[type="text"][spellcheck="false"], input[type="email"][spellcheck="false"], input[type="password"][spellcheck="false"], input[type="search"][spellcheck="false"], input[type="url"][spellcheck="false"], textarea[spellcheck="false"], [contenteditable="true"][spellcheck="false"] {

   spellcheck: true !important;

}

Can't log on to x.com. Getting this message: "Firefox's Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com".

I added x.com and twitter.com as an exception in Settings/Enhanced Tracking Protection and still not working.

What the heck firefox???

When you go into 'Manage Bookmarks' and click on 'Import/Backup Bookmarks' is there a way to clear out the list of files listed when you hover over 'Restore ->' which brings up the list of recent bookmark files that you have restored?

Good afternoon,

If necessary, I am available to add more information about this case (145005), in English or Portuguese.

I have 750mb Claro fiber internet, directly on the cable. I updated Firefox. My internet dropped to 300/340mb. I complained to Claro. They tested by connecting another computer to the cable. It gave 800mb. I installed Chrome. Speed ​​was 900mb. What to do in Firefox to regain speed?

https://x.com/ (Formaly Twitter) Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com

Not only me: https://www.reddit.com/r/firefox/comments/1ctx1bm/twitter_not_working_on_private_browsing/ https://connect.mozilla.org/t5/discussions/firefox-s-enhanced-tracking-protection-strict-mode-is-known-to/td-p/57432 https://lemmy.world/post/15496431

https://news.ycombinator.com/item?id=40386418 Dunno if entirely accurate but regarding the Firefox error: “Twitter switched their top level domain to X, but didn't change any of their other domains, so they're still pulling assets from Twimg. Which makes Firefox (correctly) block the page if you have Tracking Protect enabled because it sees X trying to involve 3rd parties.“ Slow clap.

After restarting Firefox i found I've lost all History and Bookmarks.

I tried simply restarting computer and everything on here: https://support.mozilla.org/en-US/questions/1408758

I'm on a MAC, I'm not sure to do at this point, I had atleast 10 years of bookmarks!

let me know if there's any other solutions thx

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

For months now I can't cut and paste if I use Firefox. I am not remotely interested is uninstalling a heap of adds in a vain attempt to fix the issue. I can use Google chrome and Wonderfox which don't suffer this issue. I fail to understand why Firefox is alone in this problem. I would switch to Wonderfox as a default but it only works on SSL sites. Please stop ignoring this issue and fix it. Running Windows 11 fully updated on an AMD cpu.
