The search engine changes by itself (ebay, bing, amazon, duck...), each time I have to go to "settings" to reset Google. Thank you for help

Le moteur de recherche change tout seul (ebay, bing, amazon, duck...), à chaque fois je dois aller dans "paramètre" pour remette Google. Merci de votre aide.

Hello, I use Firefox on Windows 11 . Since my computer became so slow, I checked task manager and found that Firefox is eating up my memory. It is described as Firefox(35) and is using about 2690MB. I would like to know how to reduce memory use if possible. Best regards.

‘I can't receive outlook mail today using Firefox. I receive message header but when I open it there's no message data. It works fine in Chrome. I can't forward a message it fails to connect to the server. When I try to delete messages it doesn't remove the item. Any suggestions?

I have to press the F11 key to see the menus, scroll bars, taskbar, etc but the screen then goes back to full-screen mode.

How do I prevent full-screen ?

I have a local only test ca and test web server. How do I load the CA certificate into Firefox. Adding it via "settings" did not work, the browser says Adding a root via "settings" does nothing. When I access a web server it says "the original certificate provided by the server is untrusted", in the issuer name field. It never actually shows the certificate. Adding a file to the appdata area (this is on windows 10) also fails; changing the enterprise ca settings does not work. This used to work.

I have been using the "Restore Previous Session Option" fairly often for years, but within the last few weeks the option is no longer there.

I had tried to use the Settings > Open Previous Windows and Tabs as a workaround, but it doesn't appear to be consistent.

Did something change in a recent update, or is my installation broken somehow? I tried refreshing Firefox but that didn't bring it back.

The article here shows what I am referring to and has a screenshot of where the "Restore Previous Session" option was: https://support.mozilla.org/en-US/kb/restore-previous-session#w_when-session-restore-occurs

Anyone else have this problem? Is my installation broken? And how to fix?

Just today (2-13-24) I discovered that certain functions of Outlook (web based) do not work in Firefox. All functions do work in Edge browser. Windows 10, Home version. I can read my emails but cannot delete them. I also cannot delete Junk Email and probably others, but I've not attempted others. When I try to delete Junk emails, it seems that they are deleted, as they disappear temporarily from the folder, only to reappear after leaving the Junk folder and returning to it.

Looking for possible solutions.

New computer, new Firefox install. Old computer has the Library Icon in the upper right corner when the browser opens. I imported my bookmarks, but can't figure out how to get the Library Icon positioned.

When I try to open a new tab, the dot continues to move back and forth but does not load the tab. Sometimes I have gotten the message: "A web page is slowing down your browser. To stop it close the page."

I have tried fixes suggested on the web, but no help, including clearing the cache.

Thank you in advance.

I have Firefox installed on my Windows 11 laptop. When I click on a new tab, I want that new tab to show 4 rows of icons of sites I have visited most frequently like my bank, Amazon, etc. I do not know how to set a new tab to show the 4 rows of icons. These icons show up in Firefox on my Windows 10 desktop computer but not on Windows 11 laptop.

I don't know if it is the last update, but since this week the scrolling menu on numerous website on firefox become messed up and instead having their usual limited height (like no more than 400px) when there are numerous links in the menu, they now reach the bottom of the windows.

I added some image to explain the problem with two sites: one screenshot show firefox bug, and the other is a screenshot (from edge) to show how the scrolling menu with limited height was supposed to be before the bug.

Also the problem appear even in the debug mode, so i doubt it is an extension trouble. How to solve this problem?

these last days, whenever i visits any page that fall under archiveofourown.org, i often end up with the page just trying to connect for ages, only to give up and say "secure connection" failed. and that " the authentication of the data could not be confirmed" (i don´t get an error code) sometimes it works, sometimes not. i can reach the pages fine on my phone, and on other browsers. i can also connect to other webpages so it´s not my connection that´s the issue. i use the page a lot, so this is really an issue. i recently switched over to firefox, and i don´t wanna have to switch back.

In upper right corner of the menu bar, I have what appears is a shield with a helmet (with red banner). This is followed by ever changing symbols, letters, and numbers . When I mouse over it or manually point it disappears. Removal of the pointer brings it back. This shows up on Firefox and Edge browsers. Does anyone know what this is?
