Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

I've been having an issue with picture-in-picture (PiP) mode where the subtitles and rewind/fast-forward buttons (rr/ff) won't follow the video into the small player for Disney+ specifically. I have no issues with YouTube or any other site. The subtitles and rr/ff just stay with the original video player on the site while the video is in PiP mode. I can see the subtitle button on the PiP player, but it is grayed out and I can't click it. I've updated both Firefox and my computer (Windows 11) and reinstalled Firefox, cleared cookies and cache, and still no dice. Any advice? Thanks!

(In the screenshot, the PiP player isn't showing video, but I think that's just because of Disney's anti-piracy software - I can see the video in the PiP player on my screen.)

Cannot open Analyst links on eTrade website. Looking at a particular stock and clicking on the Analysts link opens another window showing individual analysts and articles relating to their opinions of this stock. I cannot click on either the analyst's name nor the articles associated with their name. eTrade customer service says Firefox is not working well on their site. I tried Microsoft Edge and everything was fine. Is there some feature I should enable on Firefox or is this a shortcoming in Firefox?

Wikipedia render Thai fonts correctly. But it seems to render Latin texts and numbers in "TH Charm of AU" font for Thai articles, which I did not set anywhere in the browser (and my operating system). Ticking "Allow pages to choose their own fonts, instead of your selections above" does not fix it either. But it renders fonts correctly in English version of the same article. (See the attached images).

Any ways to fix this?

Thanks in advance.

Cannot Log on to Costco.com site after update to Firefox 133.0 in Win 10 pro on 2 computers. Both are up-to-date with latest software.

Entering valid account and password cause the Costco logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers. Log on to Costco via Microsoft Edge works perfectly (on 2 computers before any trouble shooting ). Logon with Firefox 133.0 works with every other site that I regularly use - Samsclub, Amazon, Yahoo mail, my own mail servers, NYtimes, WashingtonPost, Google, Walmart, and others

Trouble Shooting Steps taken with no change in the problem logon to Costco + Cleaned cache / cookies + Disabled virus protections + Disabled firewall + Stopped all security services + Rebooted + In settings | Privacy & Security: Added Costco.com as Exception for Enhanced Tracking protection + In settings | Privacy & Security: Added Costco.com as Exception - Cookies and Site Date

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

When I load PBS.org I get a message that PBS is having connectivity issues. I can load it on Safari without any problems (and my Kindle too). Is this Firefox or PBS's problem? Please help.

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.

Running Firefox 133.0 on Ubuntu 20.04 desktop

Periodically, Firefox will freeze and send the message "Firefox must be restarted to continue". After restarting, Firefox takes a long time to recover. This morning, it took nearly 5 minutes to recover.

After yesterday's update, I'm not able to access files in Google Drive using Firefox on Windows. They're greyed out, and when I try to open one, a pop up informs me "This file can't be opened because you're offline." I'm certainly online, and it works on Chrome (ugh). Anyone else experiencing this?

I believe there is a memory leak (or memory growth) bug in Firefox 133.0 on Windows 10. It's site-specific. I am trying to login to my account at https://www.ssa.gov/, and it never actually gets to the login prompt. Using the Windows task manager, I can see the RAM usage keeps increasing, until it nears the 12 GB installed RAM capacity, at which time I kill the firefox process. I'd say this is a bug in ssa.gov, except the problem does not occur with the google chrome browser.

To provide further detail, I go to site https://www.ssa.gov/, and click on the "sign in" button. That takes me to the page where you choose the login method (id.me or login.gov) and I choose "id.me". It takes me to the "you are leaving Social Security's website " message, which is still on the ssa.gov website. At that point, firefox memory usage starts to increase, as shown in task manager. The browser never advances to the next page, but main memory usage keeps going up. This goes on for about 30 seconds before I have to kill the firefox process.

I have an account with Chewy. When I try to access the link to "My Pet" I receive this message:

400 Bad request Your browser sent an invalid request.

I don't understand why or how to correct it.

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

I was working with responsive view mode and noticed that sensor scroll with mouse is broken. I checked on another PC and the problem there too. I don't know how to describe it, but I made a video and uploaded it to a website so you can watch it.

Video link (there might be ads on the site im sorry)

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

Hi,

I have been using Mozilla for decades. In the last few weeks, the browser is constantly crashing. I heard there were some large scale denial of service attacts on Mozilla and I feel like I am seeing the effects. My browser is upto date so that isn't the issue. Is there anything I can do? If it doesn't get better soon I will have to switch to Chrome or worse :-( YUK! I love you guys and really hope there is a solution.

I tried in another browser and Google Drive is online. Not on Firefox since the latest update.

Thanks in advance for any tip to troubleshoot. Internet connection is checked and okay. All the other google products are functioning as expected.

Paypal hangs when transferred from vendor site to complete purchase. Relaunching Firefox in troubleshooting mode resolves issue. Also works with Safari. What's wrong, what needs to be changed?
