Diễn đàn hỗ trợ Firefox

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

I just updated from Firefox 96.0.3 to Firefox 97. When I try to print I get the Firefox preview, even though I have print.tab_modal.enabled set to false. Please fix it so that I can get the print system dialog without going via the Firefox preview. Note that I have now reverted to Firefox 96.0.3 and won't update from this unless the problem is fixed.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Is there a preference in about:config to fake or simply block websites from reading the font-list of my operatingsystem? I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

I just downloaded the lasted "update" and suddenly EVERY SINGLE WEBSITE I visit, INCLUDING FIREFOX, is giving me a security error:, Secure connection failed, Firefox did not connect.

This is obviously something in the latest download, because the exact same sites have no problem when i open them in Chrome. In fact, it's the ONLY way I can post this problem, because Firefox is preventing me from accessing the Internet entirely.

Please fix this ASAP, or I will have to move permanently to a new browser. I can't afford this kind of disruption to my work.

DEAR SIR MAM PLZZ HAVE A LOOK

GOOGLE CHROME WORKING FINE BUT FIREFOX AINT WORKING

THANK YOU

mail me at [Email address]

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

When using Firefox I am getting PR_CONNECT_RESET_ERROR in any tab I open or refresh. Error does not happen in Chrome or Edge. Running Windows 10, Firefox 121, Kaspersky This started happening today.

I fully uninstalled Firefox and then reinstalled again, but issue hasn't been resolved. Also, I disabled Kaspersky, but issue hasn't been resolved.

Pls advice what to do, as I can not use Firefox any more.

I have turned off all extensions, allowed all permissions on the page, changed the Privacy to Standard, turned off enhanced protection, but I still cannot get the popup to show on this page (need login to see actual page)

https://app.gohighlevel.com/location/ApwnvXGFIEHm8LKgmFQz/page-builder/hKQsgETZFHVjwGxTUCeN

I cannot find anything else which can be blocking it, but something is.

If I load the page in Edge, it works fine.

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

This has happened a few times before after a Firefox update, but the most recent occurrence was after the update to version 117.0.1. My mouse wheel will not scroll in the bookmarks drop down menu, I have to use the up and down arrows in the drop down menu which is very slow. When the scroll wheel did work in the past, I could be scrolling and then move the cursor to the up or down arrows and scroll even faster still using the scroll wheel and get to the folder I want a lot quicker. The scroll wheel works normally while scrolling through webpages, the only place it doesn't scroll is the bookmarks drop down menu. I'm running Firefox version 117.0.1 (64 bit) on a Windows 10 notebook PC. Any help would be greatly appreciated, thank you.

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?
