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.

I subscribe to my city's newsletter. It gives quick links "click here" to register for a class, "click here" for information about an upcoming parade. I used to be able to click and get it. Now it tells me It can't find the site OR I might be connected but behind a firewall. There are too many options and too many terms, I don't know what to do, I just want to click links from my city newsletter, and get taken to them. Help???

Hmm. We’re having trouble finding that site.

We can’t connect to the server at vu4mbwlab.cc.rs6.net.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

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.

None of my saved passwords in my Mozilla account are showing up when I switch laptops and try to logon to various sites. Instead I have to manually enter the passwords for the sites every time even though the sites show that I have saved passwords for that site in my Mozilla account. When I type the password in a old or new site, Mozilla doesn't even ask if I want to save the password anymore.

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

snap version seems to have problem thought this might help. I am a software developer.

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?

I found that my Figma prototype works in all other broswers, but appears mangled in Firefox. I've restarted and tried troubleshoot mode, but issue remains. See attached screen shots for ramdom background color for text blocks.

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!

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.

- Adrian

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]

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

When I display a statement from Tesco Bank it opens a new tab and says that I can download or print it from there but I can find no Download tab nor anywhere in the customisation options to add one.

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.

My firefox browser being hack multiple times, so I dident use it for multiples years... Now I just want to give it an other chance by removing everything that could create trouble. When I get over the setting windows I can read this: Information Your browser is being managed by your organisation.

I don't understand, this is my private computer. How to remove this organisation management???

Dear,

I use a hotkey for the screen-capture program "Snagit". The hotkey is: CTRL-SHFT-P

However, it now seems that also the AI-search program "Perlexity" uses the same hotkey.

Where can I remove the shortkey for Perplexity?
