Diễn đàn hỗ trợ Firefox

I'm at a loss for words here. I have a website I frequent and it has a really annoying behavior. I'm a developer so finally I mustered the strength to do something about it. I googled how to create an extension in Firefox and within 5 minutes I had a working extension that solved their annoyance. However, I can only load it temporarily. If I close Firefox, it goes away. When I try to actually install it, it says I need to have it signed. I have now spent the better part of an hour trying to find out how to self sign it. I refuse to believe that I have to submit this to Mozilla for me to be able to install my own code. Can someone please send me in the direction of how i self sign and install my own extension. I have no intention of publishing, I only want to run this for myself.

In the last few days whenever I download a PDF file instead of it being displayed in my default PDF read Firefox (version 121.0.1) takes over and displays the contents of the file. I do not want this, I prefer my PDF reader! How do I stop Firefox trying to take over this function? (other than converting to Chrome)

After the last update, my add-ons overflow menu no longer works from the puzzle icon. It won't expand completely and you can't scroll down, therefore, I can't add or remove add-ons to the bar. See Image.

One of the websites I use now gives me the following error: Please unblock challenges.cloudflare.com to proceed Microsoft edge does not have this problem, but I don't like using edge. I used my search and found many causes. I did the following: Went to my firefox settings and cleared cookies and history I ran two security programs, bitdefender and maleware bytes I still have the problem.

I asked a question earlier about being blocked from a site that I frequent while using Firefox but not when using Edge. I don't use Edge much but another difference has become apparent. Many of the sites like news sites an information sites seem to take longer to open than they used to on Firefox, I can see little icons going back and forth in the tab at top. Normally this lasts for ten seconds or so then the site I was after appears. I was on Edge and noted that this was not happening. I spent several minutes going back and forth and I definitely have an issue with Firefox. I have Windows 10 running on an old desktop. I use Express VPN I use BitDefender In Firefox I use Adblock Plus, Ghostery, I use Duck Duck search

Do I need a new version of Firefox or what? It says it is up to date 121.0.1 Have been using Firefox for years and not had any issues like these. Mark

HI, I use Firefox for Kiosk system... what is not usable for this application is Firefox sending popups to remind the user of ie. "do not forget to save your data" or similar... this breaks the kiosk system and needs Admin intervention... I love FF, but how can I suppress these support popups in this environment?

Thx Dan

Up until this last update, in Gmail inbox, each message could be moused over top and action icons would show up. This no longer happens and I don't know why. It was very convenient not to have to open the message to take action on it and then return to the inbox. Now if I click the checkbox on the left side of the message those icons appear, but I never had to do this before??? I have not made any changes to the settings on my 1 year old Macbook Pro or Firefox configuration...

After the latest Firefox update (121.0.1) , I have been unable to use Firefox to log into iCloud or my Merrill Lynch account. I have to use Chrome instead. Other website log-ins seem to be ok.
