Was researching cookie management techniques in GROC where AI suggested I go to the DevTools feature in the Firefox browser, go to the Application tab & expand cookies in the side toolbar. However, I’m unable to find DevTools

Hi! I had a firefox account when I worked for the law firm McCormick Barstow a few years ago. I haven't worked there for a few years. I just set up firefox on my personal computer, but am having problems changing my primary email from my work email (gina.axsom@mccormickbarstow.com) to my personal email (gaxsom@gmail.com). Can you help? I have no way of receiving any codes going to my old work email address which no longer exists. Thank you, Gina Axsom

On outlook.com sign in with password does not work. It gives "Please retry with a different device or other authentication method to sign in." Works fine in edge.

I have an issue where the following operations with the "new" profile manager don't work: - setting up a new profile (about:newprofile in the new profile is just blank) (a new profile gets created though) - deleting a profile (about:newprofile is just blank) - editing any profile that is not the original profile (about:editprofile is just blank) (works with the original profile) - the select profile interface from the account or menu button is blank when opening it from any profile that is not the original profile

What works tho is calling about:profilemanager from any profile. From there any profile can be selected and switched to.

I'm using the Bazzite (Linux distro that is Fedora based). I'm fairly new to Linux so that could be a issue, the problem was there from the get-go though and since Firefox was preinstalled I don't believe I could've messed up much.

Firefox version is 147.0.4 Bazzite version is 43.20260211.0 (Kinoite)

Reboot doesn't fix these issues. Uninstalled Firefox with deleting user data, installed it again and same behavior appears again.

I also tried installing a Firefox fork (Waterfox). It had the same issues.

I would appreciate any help and would be willing to share more detailed date if it helps somebody help me.

The attached screenshots mostly show the UI that is not working as expected.

when I start the browser, alongside homepage, it opens a new unknown page (which I've never searched and opened myself before) with extremely obscene content. for example https://playafterdark.com/click? thanks god, my children haven't seen it yet how is it possible?

Last week I went to my Firefox browser, my main browser for years, only to find the background is a disturbing pink and all my bookmarks are gone. What happened to change my data and page...did I do something to choose a new format?

for about 8 years now, on and off, on hundreds of OS-es, clean installs of firefox etc. sometimes - not always - typing into the firefox search bar and pressing enter does nothing

i have bit-warden, u-block-origin and stylus installed (but they shouldn't be running on the 'new-tab-page' - is my firefox sync-profile containing some firefox-breaking-errors? (latest Win-11)

I retired an older desktop unit several months ago and am no longer able to access the bookmarks associated with my account. My profile information now says account disconnected, followed by my email address. Below that the words Profile 1 appear. The menu below is the regular menu for actions on Firefox but none of the bookmarks from the original computer appear. Is there some way to access them?

bold text Firefox has been my browser forever. When I tried to open it this morning I was invited to create a profile, so no profile, no Firefox..... I've never had to do this before and am reluctant because of the apparent threat of losing all my passwords and bookmarks. I'm 85 years of age so don't need this complication. Any help would be appreciated, complicated high tech answer will probably be beyond me. Brian.

Just the last couple of days I can no longer browse through the images of an ebay item. the first image loads but the arrows or the thumbnails yield no movement, and I can't use the contact seller button either. No other website is effected, I am using the latest Firefox with Ventura on an imac. It all works if I use Duck duck and go? All very strange. Tim
