Firefox Support Forum

For the last few weeks I keep getting this error message: An error occurred during a connection to ....... You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

It will suddenly happen for multiple sites that I have been connected to in the past, or new sites I try to open including support.mozilla.org. A solution is to clear my history and restart the browser. It only happens on my windows 10 laptop. I think happens when I have logged off or the device has slept and then firefox has restarted and opened previously open tabs. Other devices on the same network don't get effected.

Hi, current version is 100.0.2. Running on Win 10 (10.0.19044 build 19044). Have refreshed Firefox and also tried a clean install - problem still exists. Have done a scan using HouseCall - no gremlins found. For the last few weeks my browser has been playing up. After a few minutes pages would basically stop loading, clicking on a new link would open a new window but nothing would load. Disabled my Ad Blocker extensions (I had two) and issue resolved itself. Re-enabled Ad blocker (AdGuard AdBlocker) and problem returned. Disabled it, problem went, tried Ghostery (not used before), issue returned. Both extensions are recommended. Similar issue exists on my work computer - one ad blocker and after a few site visits pages no longer load, and links no longer react to a click, home button no longer works. I close and open and I get told firefox is already running and do I want to close it before opening again. Pretty sure it's not just my home computer. Any help would be welcomed.

in startpage of my ms account all ms apps can be opened...........EXCEPT the app Onedrive. What to do to make this work?????

using MS Edge all is doing well!!

thanks in advance

Hey! I think to migrate from Vivaldi but only couple of things stops me. I used to split some tabs in one screen there and looks like I can't find any good addons for that. There is one addon Tile Tabs WE but it is not what I need, I want to tabs be still along other tabs, I can detach them and place on my screen by myself without such addons but that's uncomfortable to use.

I'm having a problem related to an extension that I have to use to consult legal processes in my country (there is no other way, the extension is widely used and is a requirement, I've always used it). Not too long ago this browser started having problems with the extension that hurt my company like hell, this is our last attempt to continue using this browser.

When opening History the column headers are there but no dates are shown in the Added and Last Modified columns. These columns are selected in Views and the listed web pages appear to be correctly sorted into Added date order. My browser is up to date an is 100.0.2 64 bit. Thanks

I KEEP HITTING ALTERNATIVELY :"dismiss" and "delete from history" but some i have to do it 40 0r 50 times before it stops popping back up

GARBAGE SOFTWARE

I cannot install English GB dictionary for my spell checker. When I click add dictionaries it takes me to a page where I can select Englsih GB as one of the dictionaries available in my locale. It then takes me to the info and remove page for the dictionary but there is no option to install and no pop up to start the download appears.

My shortcut display had frequently visited websites shown and these have been replaced by several sponsored shortcuts I am not interested in. Plus, my saved user names and passwords are not loading even though they are still stored. I don't understand what happened, why these have changed, or how to restore what I previously had on shortcuts. I am not a tech savvy person and am stumped and looking for help

For the last several FF versions, although I choose a light theme, the pull downs/menus always wind up dark with white text. It also shows up when I am editing options in FF itself. How do I stop this? I want a light background with black/dark text.

I must have deleted??? my sent messages or moved them to somewhere. But they are ALL gone. where did they go? And most importantly, how do I get them back?

My DSL is Comcast Xfinity & I use Firefox is my browser. I also use MSN.

Its difficult to get help with firefox even though I have been using it for a long time. 1. everyting when I open the browser it tells me that it is not responding. 2. Then once it opend up it tells me that the firefox is already running and that I need to close the old one before the new one can run.. 3. It just seems that the browser with all the updates run slower and slower with each updates.. 4. I find it difficult to get a hander on running firefox...can you help?

Our printers are added from a print server. FireFox is showing the full printer server path as the printer name. This is not good. Why is this happening? I have tried clearing the printer settings and re-adding the printers but this did not fix the issue.

After a reinstallation of FIREFOX, it failed to login to sync with Firefox. My account and password input are correct. And I can login to my accout with Chrome (https://accounts.firefox.com/).

my OS: ubuntu 18.04 firefox version: 100.0.2

Hi there, I have been trying to get into a Government site that I have to use and I continually, only from today, get a message saying the Certificate is outdated. What can I do to override this issue? Cheers!

PC / Windows 7 (yes, still) / Firefox 100.0.2 :

Past several months on Firefox, when attempting to access a video either embedded (say, in a news site or YouTube), the download is unusually slow, with such screen notices (attached) appearing.

The "gray bar" across the bottom (which, as I understand it, indicates buffering/caching activity) immediately loads up about .25%, then awaits the video to play . . . and then it sits there and goes through any combination of the attached .jpgs.

Quite often, regardless of how many tabs are open (perhaps a half dozen), the (Not Responding) message will show up, and then it's just wait it out (usually 15-45 seconds).

Any solutions / comments / directions-to-point-me-in?

Appreciated. Thank you.

How do you save the changes you made on inspect element on firefox?

All im getting is youtube videos of how to do it for chrome and you require an extension!
