Firefox is verified Broken! Whatever Firefox did with its last update is causing major problems. Spent hours with the internet provider and websites trying to figure out why could not access webpages and internet accounts.

Firefox is taking forever to load pages and often just times out or never actually loading the page. When I can get to a page, something is interfering with account access on webpages. Spent 3 hours with AT&T where they monitored trying to access my email account.

Could access with Edge, Chrome and Safari. However, Firefox is dead and will not allow me to access websites as pages do not load or interferes with account access.

Mozilla support needs to fix this issue ASAP or I will be forced to leave Firefox for good. I know I am not the only one having this issue! I was willing to put in the effort to verify if Firefox was actually broken or not!

Today I suddenly started receiving the error code: SEC_ERROR_REVOKED_CERTIFICATE on a secure authentication page that was working until a few hours earlier, belonging to a major national bank.

https://www.ssllabs.com/ssltest/ cannot reach that page, other SSL checking sites report variable results (some say one cert in the chain has expired after a CRL, others say all is OK)

The same page/site works flawlessly on Chrome. Firefox incompatibility with popular portals is a growing trend unfortunately.

After a little digging with developer tools, it comes out the OCSP query reports the REVOKED_CERTIFICATE error. Disabling the "Query OCSP [..]" option in Firefox that website starts working fine again.

Now, I would like to still keep using the OCSP queries ON, and I definitely want to keep using Firefox for everything.

My question is: when a portal or website is found to be broken with Firefox (with default settings), with a root cause found like in this case, how can it be reported?

Having a clear report path would be useful to try to make the browser more compatible (in this case : was this a bug? Some wrong information on OCSP responders? Some mess caused by the website mantainers?)

I want my emails to be listed with the latest up top, and then chronologically. I have selected countless times "unthread emails" but it's not listing mails separately in chronological order. It's especially frustrating as I want Firebird to be a viable alternative.

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

Dual folders in Thunderbird: such as "Sent & Sent Mail", "Drafts and Drafts", "Bin and Deleted", "All Mail and Important", but the final answer in the earlier thread just doesn't work for me. How can I delete these annoying duplicated folders? I am using Gmail, and also a provider-specific email (BT.Com) and duplicate folders appear there, too: "Sent" and "Sent", "Deleted Items" and "Deleted", and "Unwanted". How do just delete the unwanted folders? Thank you

My computer crashed, but luckily I had a good backup. I had to reinstall thunderbird, which brought easily all my email back. However there were group lists in thunderbird that are gone. How can I retrieve them? The list would have had one name, but would have 20-50 people on the list. What to do?

Thanks in advance!!!

I'm experiencing an issue with Thunderbird that started unexpectedly. Whenever I try to access my email, I get a warning message saying that "The site certificate is not valid for this server. Someone may be trying to impersonate the server. It is not recommended to proceed."

I'm not sure why this error has suddenly appeared, as everything was working fine before. I haven’t made any changes to my email settings or installed new software recently. Has anyone else encountered this issue or knows how to resolve it?

My hotmail Email page stopped opening yesterday morning. I can open the Live.com page on my Android phone and Safari. I Don't like Safari, and I want to be on Firefox on my desktop.

I have used Firefox for years with no problems. The past month, however, I am encountering many problems with my often used web sites. What is going on? I make a purchase and cannot proceed. I have not added any new blockers or anything.

J'ai changé d'ordinateur.Mon installateur m'a installé Thunderbird et je ne retrouve aucune trace des mails que j'envoie...Cette fonction n'est-elle pas prévue sur Thunderbird?

As the title states, certain media elements within Firefox refuse to play with audio, but only with frustrating inconsistency. For example, any videos on Youtube are fine. Any videos on Reddit are fine. But many videos, most commonly on boorus and streaming sites I cannot name here, will not play. The volume on the video slider is all the way up, the Firefox application is not muted, the site is not muted, and the tab is not muted. The only thing that makes those videos play audio is if I left click on them to open them in another tab by themselves. While it solves the issue, it's still an extremely inconvenient way to go about my browsing. I know for a fact that this is a Firefox problem because those same videos on those same sites work perfectly fine within other browsers. Please, does anybody know of a solution to this issue?

Firefox has become exceedingly slow. I have used Firefox for the most part going back to the beginning save a 2 year stint when Mozilla fell behind and did not update the product in the early years after ver 4. However, the slowness of Firefox is so bad now that I may have to find or use another browser! It is literally that bad! This problem is recent as in the last 45 days as far as my individual needs. I have already gone through the troubleshooting list and made the modifications. That seemed to work for a day or two but the slowness of Firefox is progressively getting worse with each passing day.

The speed is like 3 minutes to 10 minutes when just trying to open a known and commonly used bookmark. Checked against Edge which came with Win 11 and Edge loads within a second or two. So, the problem is not hardware or internet connection. I have one of the fastest speeds on the planet with a true fiber optic connection as I am close to the backbone location in my city. We are talking 2.1gig down and 820MB up. Tested against two different speed tests. The problem is with Firefox specific. Mozilla needs to address this issue as it seems to be an ongoing problem across several IOS platforms.

I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

Greetings Customer Service @ Mozilla While attempting to Turn on Mozilla Firefox Extension to Intensify the Detection Technologies through my Kaspersky Premium Software, I received the following error message:
