Diễn đàn hỗ trợ Firefox

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.

I can login from other web browsers, but not Firefox. What's going on?

When I try to login as I have always dine in the past, this is what comes up: https://outlook.live.com/mail/0/

But then absolutely nothing happens. Please advise.

Every time I open a youtube video in fullscreen, firefox crashes. `about:crashes` says "No crash reports have been submitted."

Some information about my system:

• Firefox version: 122.0.1 (64-Bit)
• Macbook Pro M2
• MacOS Sonoma 14.3.1

If there is a way to get more information that you would require (like logs) please describe how I access them, so I can share them.

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!!

i use New Tab Override, reinstalled my software, firefox, and lost the button to get a new tab that goes on the address bar. its no longer in customize. ive removed the addon and put it back on, started in troubleshoot mode, disabled all other addons, and it never showed back up

I'm trying to give permission to a website to use my microphone, but if I copy in the web address, the "Allow" button doesn't appear & so when I hit "save changes" nothing happens.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

Please explain: Access Denied You don't have permission to access "http://www.rei.com/user/login" on this server.

I opened Private window in Firefox desktop browser for Mac, to login to gmail account. After few minutes of usage, I closed the Private window. When I opened a new Private window the 2nd time and open gmail.com, I could see I am not signed out of the gmail account. This is breach of privacy and highly unacceptable.

Why is my account still logged in, even while using Private window? What if I was using this in a public computer? Utterly scared now of my privacy and security in using Firefox.

I cannot clear this cache to zero no matter what I try. How can I clear this cache. It just started happening after a recent update. I clean my caches after every use but not any longer.

Amazon "Returns & Orders" page will not load... Mac/Firefox computer even it trouble shoot mode. Page just continues to partially load and repeats until I stop it.

I find this does not happen when I opened Mozilla and searched for an answer, but if I am in almost any other site, and click a link, it oens in a new window and is so narrow, it is unusable until I stretch i. This is a pain, and never happened ubtil about 1-2 months ago after an update.

Please let m know if anyone has a solution to this irritating challenge.

The Send Tab/Link to Device feature only works in one direction, from iOS to MacOS. iOS to iOS never receives, although the popup says it sent. I'm using Firefox 98 on MacOS and iOS. I have a Windows 10 PC which can't receive or send tabs/links as well but I'll limit it to the Apple devices for the moment.

Sync and notifications are enabled on Laptop, iPhone, and iPad. I've de-synced and re-synced each device separately and together. I've attempted to send between each device separately and all together.

Neither iOS device can receive tabs/links from one another, nor send to each other. Laptop can receive tabs/links from both iPhone and iPad, but not send to either.

Each time I re-sync an iOS device I get a notification on the Laptop saying that "this computer is now connected with Firefox iOS". But still nothing works.

and not only that, when I click on sign in - it shows me a work email address that I rarely use - not my Firefox account / main email. I have to click NEXT then change email address from the drop down menu. I followed the setting attached. but it's still does it. I close Google tab, then go back and im signed out again! It's extremely annoying. How on earth can I fix this?

My tech info: Macbook Air Mac OS 12.2.1

Is this a scam? I just did a search for a local pub here in Boise, and receive the following: You've made the 5-billionth search. Congratulations! You may be our next lucky winner!’ for ‘Firefox

I'm trying to recover a profile that has the most recent history, tabs and pinned tabs that I seem to have either lost or overwritten yesterday. I can try to reconstruct from my actual history but I don't remember everything I had open. I'm also not sure what to do with all the profiles that are associated with my browser. The version with my actual name is not the default and is an initial version I used on an older computer.A ny easy answers would be appreciated. It's frustrating that there is no way to contact them Mozilla directly.

Thanks
