Firefox 社群討論區

My previous version of Firefox was on the fritz and I was afraid there was malware in it so I uninstalled it. When I reinstalled it I realized all my bookmarks were missing and I can't figure out how to restore them from my profile or a previous backup. Please help! Thank you.

After the latest update I could not access any websites

I thought it was the VPN I just installed, so I uninstalled it, but that still did not fix the problem.

I did 3 system restores and still it did not fix the problem.

My browser had changed and I spent hours trying to sort this problem out.

I uninstalled Firefox and then re-installed but still had problems connecting to the web.

Then when I was going to uninstall Firefox again with a special program, it gave two choices, uninstall or repair. I selected repair and sure enough I could access the web

All my browser extensions on tool bar had disappeared

The tool bar was full of junk, so I used Customised Toobar and finally fixed the problem.

I have disabled auto updates

Thank you Firefox for the inconvenience you caused , but I forgive you, because I consider you provide the best browser to use for access to web

Having this issue with Youtube since a few days ago, on version 115.0.2 and 115.0.3, and only for videos encoded in AVC/H264. VP9 and AV1 encoded videos have no trouble buffering, only H264 is affected. Happens with or without adblocker, and on different OS. Cookies cleared, no dice.

Video would load the first 20-40 seconds, then does not buffer at all subsequently once it reaches the end of that portion. I have to skip a few seconds forward for it to load the next 20-40 secs, then it would get stuck again.

I can get around this issue by either lowering resolution to 480p (which looks terribly unwatchable), or turn VP9 streams back on (which does not work correctly on my setup, there's a driver bug that hasn't been fixed).

The sure way, and strange thing, is that AVC/H264 videos load and buffer with absolutely no issue when I'm logged out of my account. Also, works with no issue in Chromium, even while logged in.

Anyone facing this or similar issue recently too? Is it still ongoing for you?

I encountered a Problem since the last update. When watching a Video on Youtube, the Playback is flashing, especially on green and red colors. I did see some People mention a similar issue years ago, so I followed the same troubleshooting by disabling Hardware acceleration and all extension. The Issue keeps persisting I am browsing on a M1 Macbook Air - no other Browser on my System has that issue. Here is an example with Screengrab https://imgur.com/a/EFrzzAD

so i have sync enabled on both devices and evrything sync perfectly except the tabs opened on my iphone are not showing on synced tabs section on my desktop firefox but the open tabs on my desktop frirefox are showing on my iphone synced tabs section btw i reset sync and signed out and signed back in and everything synced but my iphone open tabs still not showing on my desktop client

Their homepage says - "Firefox’s most recent update (v.115) is having issues playing the livestream. NPR Digital and Firefox have stated they are investigating the issue. In the meantime, we recommend listening with another browser (e.g. Chrome) or device (e.g. mobile app)." Will there be a fix???

Recently, my FireFox has been acting a bit strange when it comes to playing videos. I am using a site called Udemy to watch a video course I'm taking, however, the videos don't seem to play for either a long time, or until I tab into YouTube and play a video there.

This issue is not only with Udemy however, as the YouTube videos also take longer than normal to start playing; It's not only at the start of the video either (whilst waiting for the video to fully load), It's all the time, between every pause I have to wait around 3-4 seconds before It actually start playing.

The issue is clearly something to do with videos but I find it very strange that playing a YouTube video forces my Udemy video to load.

It's been a real struggle trying to get todays course day done, since every time I pause the video I end up having to wait a while or go to YouTube and play a video to make it continue.

I've gone through all the basic troubleshooting recommended for video issues on here and other places: Turn of hardware encoding, lower security levels, enabling autoplay etc etc; absolutely no luck. I've tried disabling extensions one by one, disabling themes, running FireFox in troubleshoot mode, clearing all data/history/cookies/cache, making sure DRM-controlled content is enabled as well as trying it disabled. You name it, I feel like I've tried it at this point... Any suggestions are highly appreciated!

Another thing to add is Chrome isn't having this issue, neither is Safari.

I have just had a new update 115.0.3 and again it has blocked most of the internet sites (all working yesterday no problems) due to secure connection failed.

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

This is about the 3rd / 4th time it has happened this year alone.

Are you not able to produce an update without blocking over 80% of internet sites when updated?

The strangest thing is other browsers are able to connect to all of the sites.

I'm a web developer working on an app running in Docker on my MacBook. Chrome, Edge and Safari trust the self-signed certificate that has been imported into the Mac's root certificate store and have no security issues, but when I try and access the web app, I'm hit with "Warning: Potential Security Risk Ahead" and the error code is MOZILLA_PKIX_ERROR_CA_CERT_USED_AS_END_ENTITY

I really miss Firefox, particularly the multi-account containers feature. What do I need to do so that Firefox will trust my certificate for my local web app?

Some websites like youtube, twitter, reddit and maybe many more don't properly load. On youtube videos freeze after a couple of minutes, I don't have any of these other issues on other browsers like Chrome

In settings when I am in security I have Firefox as my default search engine. When I go into the search tab it tells me Bing is. There is a drop down box to change it but Firefox is not an option. Help I am also unable to get into my xfinity email so please respond to, [removed email from public] Thx

Hi I have re-installed my Windows and all data have been backed up in my Firefox account. I have a problem with history and bookmarks which are not restored in my new windows but my password restored.

I've tried all the ways mentioned to delete my search history, other than deleting each entry individually. Three particular websites just won't go. Is there some umbrella action that will delete all these references?

First, I am not tech savvy. I deleted my browsing history but, I see a new list of recently searched places. It is listed as Firefox suggests: then identifies my desktop and recently searched websites that are no longer needed. I want to be able to delete these tabs, or whatever they are called.
