Firefox Community Forum

The past two days Firefox has not been displaying PDFs properly, turning 2 out of 14 pages sideways. I restarted my computer but no change. The PDFs display beautifully in Edge.

Clicking on any article at ncronline results in just First Letter of text appearing. Some links appear as well. This occurs at no other site. Using EDGE, I have no problem at the site.  ??

Telemetry upload is enabled even though all the checkboxes are de-selected in about:preferences. about:telemetry shows: Telemetry is collecting pre-release data and upload is enabled. I have all the telemetry prefs set to false as well.

``` 33 matches for "telemetry" in buffer: prefs.js

My console is stuffed with errors of firefox trying and failing to send telemetry pings.

Dozens of these accumulated very quickly.

Hello.

For the past few months, I've been experiencing severe issues with performance that I noted appear only on YouTube. I have not noticed this on any other website. The site is unresponsive, takes a long time to load, key presses (pause, skip 10s, etc.) are registered with a massive delay. It is generally very unpleasant to use.

I have tried disabling all extensions, clearing data, I even reinstalled the entire operating system once for a different reason and the issue still persisted. I launched YouTube on different browsers (Chrome) with no performance issues at all.

I lived with this problem for a long time now, but recently it's becoming unbearable. I prefer Firefox to Chromium-based browsers, but as YouTube is a site I visit very frequently, I will unfortunately consider switching to another browser.

I have not found any useful resources regarding this issue on the Internet, it seems like it's not a common problem.

Any help is appreciated.

Hi,

I know that Google's doing everything to push everyone to use their spy software Chrome, but now youtube is really slow (15 seconds to stop a video when I click on the video, same to start it, 10 seconds to open a new dongle for youtube, and roughly 5 seconds waiting in others services).

Also, some others website work very badly or sometime not working at all with Firefox, why ? I have Ublock on Firefox too

I came back to Firefox for my privacy but if 35% of websites not work with it, not great. Have you an idea how to solve this problem ?

Thank you,

Matt

While in ProCore I will open the drawings and Firefox will present it correctly with the markups tools. After 2 or 3 drawings the markups box will no longer show up. I have to go to Firefox settings and delete the cache, restart ProCore and the drawings will go back as they should be.

There is no audio on any website in Firefox only. I'm using Windows 11

1. Numbered list item When a video is playing there used to be an audio icon showing the tab is playing audio, this does not show anymore.
2. Numbered list item Firefox does not appear in the Windows volume mixer
3. Numbered list item The Firefox Task Manager Utility 'Windows Media Framework Audio Decoder is always idle.
4. Numbered list item I've restarted the Windows AudioSrv service and Windows explorer process

Nothing works. Please help.

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

I woke up this morning and realized my youtube wasn't working right. It was loading endlessly and wouldn't play right away when I clicked a video. I thought at first it was a computer issue so I restarted it; but that didn't change anything. Then I thought it was an internet thing, so I switched to my mobile hotspot; but still nothing changed.

I've restarted my computer 3 times, restarted firefox 9 times and done just about everything I could find online. I turned off the recommended hardware settings, went into troubleshoot mode (although I'm not tech savvy so I didn't really understand what to look for), made sure firefox was up to date, cleared my cache and cookies, made sure all my add-ons were up to date; and still nothing.

And it's the same for Twitch. It just loads endlessly and doesn't play anything. It doesn't give me an error or a bug notification; just shows the gracy spinning circle and nothing else.

The only way anything loads is if I turn the quality down to the lowest one possible and have it paused for a minute to let it load on its own.

It works fine in Microsoft Edge; but just not in firefox.

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Running Windows 11 Pro (Clean windows setup not long ago and the issue was there from the beginning.) German Language Firefox 116.0.2 Build ID 20230805021307 Intel CPU i7-1360P, 16 GB RAM, 1TB M.2 SSD

Would really appreciate a solution for the issue because I really like Firefox!

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You

I have followed these instructions for deleting all bookmarks at once but Firefox isn't responding to these commands so I have to delete each bookmark individually. To delete a lot of bookmarks at once, use the Library dialog. Either: * Ctrl+Shift+b * Bookmarks > Show All Bookmarks In the left panel, click Bookmarks Menu. In the right panel, click the top item you want to remove, then press Shift+End to select all the way to the bottom, then right-click > Delete.

Two days ago, my firefox browser started not restoring the previous sessions. I changed nothing in the configuration and I don't remember I had a crash. The option "Restore Previous Session" does not appear in the "3-bar menu > history" and it appears grayed in the History Firefox main menu.

What I've already tried or verified following the instructions of mozilla forum: 1) Settings > general > “Open previous windows and tabs” is checked as it always have been; I unchecked and and rechecked but nothing changed; 2) Settings > Privacy & Security > “remember history” is selected. Also tried to Settings > Privacy & Security > "Use custom settings for history" with "Always use Private Browsing mode" not checked. No success 3) I also deleted sessionstore-backups folder under my profile. The new created folder, even after closing some new sessions, has only the "recovery.jsonlz4" and "recovery.baklz4" files. There is no "previous.jsonlz4" inside which seems weird. 4) through about:config I checked that browser.sessionstore.resume_from_crash was true. In fact, I have Firefox in a second computer with no sessions restoring problem. I compared all browser.sessionstore.xxxx variables and the values are the same.

I still have the problem and do not know what to try next. Reset Firefox?

Audio on my PC works except on the firefox browser. The browser is not muted, I've checked the volume mixer, i've reinstalled firefox, but nothing seems to work. This just started occurring a couple days ago. When I restart the pc, i will get audio from firefox for a couple seconds then audio stops.

While reconnecting one of my computers to my Firefox account I saw at the top of the Settings Page: "Your settings are being managed by your organization". Problem is that I don't belong to any organizations or enterprises having anything to do with my online life. I have been hacked in the past and am paranoid when I see something that doesn't make sense. When I click on the link (trusting that it is indeed from you), it takes me to your Enterprise Policy page showing the following:

Active Policy Name Policy Value

DNSOverHTTPS Enabled false Locked true

I always use secure DNS (DOH or DOT) on everything - network adapters, routers (except the ISP one whose default I can't figure out to circumvent) etc. but on the browser setting pages I am only given the option of having it off: the default, increased, and max protection options are greyed out and cannot be chosen. I guess that explains the policy values but who locked it? My only guess is that is use a Surfshark VPN and realize that in so doing I am using Surfshark's DNS servers but I believe I had this problem before using the VPN. Any help would be greatly appreciated. Thanx.
