Ever since I updated last week, one website that I use will not work. Whenever I try to log in to the M&T Online Banking website, it blocks me and says "M&T Online Banking Is Temporarily Unavailable." The app works on my phone and I can log in through Chrome, it's only on Firefox that I'm getting this problem. I called M&T Bank and they confirmed that it's a problem with Firefox. Something is blocking me but I don't know what it is. I am not using a VPN or adblocker.

Why do numbers appear next to some of my shortcuts on my Firefox shortcuts home page? See attached. I only have one tab or window open and this number (5) has incremented over time.

My computer displays were dramatically different one morning a couple of days ago, as MS Edge seems to have overtaken control of my system, which included changing the displays on my monitors. I have restored the system to a few days ago when the system was correct, but the restore resulted in the same Edge displays. With considerable effort to overcome Edge, I have also made Firefox my default browser. After resetting and restarting, my One Note pages are still no longer available and my displays have not changed from the Edge-changed ones. Any additional ideas? Please?

When I open Firefox browser around ten several weeks old tabs are there. It is not set in the setting to open. I did many attempts to get rid of this nuisance and they are still here. I Created new profile, erased all profiles, removed Firefox, and reinstalled with option not to use old setting since new installation found that the fire fox has been installed. And frustration part that Mozilla do not offer (as I know) support to fix this problem. This glitch is hidden somewhere and the program always find it an put it back. I am not sure if what to do as I run out of options, other than turn to another browser after many years using only Firefox with no problems at all. Thanks Ned

in settings Homepage and new windows use custom urls, current urls doesn't include Pinned tabs. Windows updated and when firefox was restored two windows were opened, one was blank and the other opened old home page settings but did not reopen all my pinned tabs, gmail, yahoo mail,and some other tabs I plnned, there are 5 of them and several regular tabs I had open before and most of them did not show up in history. Pinned tabs do not get included in use custom urls for the home pages. Also for several days my roboform bar would not show up, roboform said no open browers to attach to when firefox was open.

I have FullShot 10 which used to show my extra buttons in the FF toolbar. A few updates ago these buttons have disappeared from FF which is really inconvenient. Those buttons still appear in MSFT Edge. I cannot take a screen capture because taking a screen shot automatically makes the FS10 buttons disappear. FF10 is not add-on to FF, it is just a regular program to easy capture graphical screen information. FS10 has not been updated/altered in any way since its installation

My e-mail will not load sub links. It pops up a list of links not related to the e-mail. Stated when I installed avast. Took avast off. DID NOT fix problem. What now???

New update to Zen browser this morning, indicated that Roboform extension needed to be updated. Uninstalled,re-installed Roboform extension. Zen browser does not seem to use the the extension - no offer to fill passwords, etc.

Can I revert to previous version of the browser?

Dear Support Team,

Ever since updating Firefox to the most recent version my pause/play button does not work with tabs open. (like youtube, spotify(browser) etc.)

I tested for mechanical issues, but those do not seem to be the issue, as the key itself work perfectly fine. Different apps (like netflix, and spotify(desktop)) do not have this issue.

If you require any additional information in regards to this inquiry don't hesitate to ask.

Additional Information

Firefox 136.0.1 (20250310180126) Installed on: March 12, 2025 at 8:50:54 AM Status: The Update was successfully installed [copy and pasted from settings]

I'm trying to get my settings & themes back after an update, and nothing is working. I can't even open bookmarks on the bookmarks toolbar. I just get "new tab" with the dots moving like it's searching for a site.

Hello,

I want to open this URL: https://compatibility.plantronics.com/deskphone Firefox 136.0.1 tells me: SEC_ERROR_REVOKED_CERTIFICATE

The same URL opens in Chrome and shows no sign of a security problem, as far as I can see (Chrome info attached).

What could be the cause? Firefox being to strict or Chrome just too relaxed?

Thanks in advance.

Hello,

My university requires me to logon to use campus services every 24 hours. Upon expiration of the logon credential after the 24 hour period, a logon window will prompt to re-enter credentials. The problem is that it will continue to prompt log in with new pop up windows every few minutes so if I don't log in, for example, over night, I'll wake up to hundreds of log on window pop ups. This creates system wide slowdown due to memory resources being maxed out. I can't enable universal pop up blocks as the systems I require use pop ups and having to open each pop up manually does work in my workflow. Any solutions? Thank you!
