Firefox Support Forum

I haven't deleted my browsing history since 2021 September, but I wish to restore browsing history from 2021Jan-2021Sep for some reasons.

I am using mac, latest version of macOS and latest version of firefox. I have read some similar articles (https://support.mozilla.org/fy-NL/questions/1290163) but it doesn't help. It says I need to go through "Start" > "Search" > "Tools" > "Folder Options." . I cannot find folder options, and I cannot find index.dat inside my mac. What can I do ? Any help is appreciated.

Same as question 1337885, which was marked "solved", despite never being solved. (Solved for a few months is not solved!)

Does every user seriously have to go through the rigmarole of manually editing a CSS file in order to have a usable UI? (as per https://ourtechroom.com/tech/get-back-old-tab-design-firefox/, for example)

I can't get my email [edited] @att.net l. It says: Secure Connection Failed

Hi, I have been working on a old project for one of my clients and found an issue. The firefox version i am using is 95.0.1 64bit version. After signing in, inside response headers from the server i am getting

set-cookie MYSESSION=eyJ***** HttpOnly

which is then used on next request i make to the server as Cookie MYSESSION=eyJhb***

But after upgrading my firefox version, although i am able to see the response header sent back from server, but it is not being sent in request header for the next api call.

Also this issue is only for localhost, works fine in production https urls

I would like to know what has changed in new version in terms of handling the response headers, thanks!

I've been considering switching to Firefox from Chromium for quite a while. However, there's one feature in Chromium that I can't do without: the task manager. In Chromium, I'm able to stop a tab's process, but the tab still remains open, displaying an error. Even if I refresh the tab, the tab's process restarts as if the tab was just refreshed, without any crashes. I'm aware that Firefox also has a task manager, but when I stop a tab's process using Firefox's task manager, the tab closes as well. Is there a method to forcefully stop a tab's process without having to close the entire tab? Perhaps there's an add-on that can help with this? I typically have a large number of tabs open — more than my PC can handle — so this feature is essential for me.

I don't use "Clear history when Firefox closes". All cookies from other sites in exception list are saved. I added both https://mail.yahoo.com/ and https://www.yahoo.com/ to exceptions list but it didn't work. Then i tried with removing https://mail.yahoo.com/ from exceptions because in saved cookies list i see only yahoo.com, but again no effect. All permissions in Page Info for both mail.yahoo.com and yahoo.com are default.
