Often after restarting firefox 148.0 … … 

… … for whatever reason, it comes up "clean".   Despite asking for tabs to be restored, they often are not.

I have about 7 tabs that I have pinned (i.e., gmail, penzu, contacts, etc).

Is there a way to have this happen automagically when started?

Doesn't seem obvious to me.

Thanks, FJohn

FF 148.0, Intel Mac, current 15.7.4 (Sequoia)

In the middle of a browsing session I needed to consult my substantial browsing history and found it to be gone. I quit FF using the dropdown and restarted. After restarting FF the browsing history showed only that session and the TST sidebar with many tabs didn't display so I concluded FF created a new profile for startup but using my home page. I have the profile in use at the time (profile_a) and a month old backup of it. profile_a seems to have all the expected data and the bookmarks are correct. I've hacked around within Profile Groups and profiles.ini but FF refuses to use profile_a in spite of my edits, and worse is silent about it so I'm stuck and need help.

Possible related issue: is TST sensitive to the number of tabs? I'm a hoarder and find TST easier to use than bookmarks so had about 700 tabs stashed in TST.

UPDATE: efforts to fix this have revealed that it's likely the release of Profiles didn't cause this problem although I speculate there might have been an inadvertent time bomb in the release. I will open a different question searching doesn't turn up the fix. If I would delete this post if possible.

FF 148.0 was running on MacOS with my profile as a folder (e.g, trb618r9.default) under Firefox. When I looked in history it was empty so I restarted FF, none of my tabs were there, and TreeStyleTabs didn't display. Investigating I see a new folder named Profiles that has a profile in it with the trb618r9.default name but not all the data in the original trb618r9.default. I renamed the "new trb618r9.default" and moved the original trb618r9.default to Profiles and restarted FF but still am not seeing the original fxxx data which still exists.

Screenshot of finder before I renamed etc. as described above shows the two same named profiles.

How can I recover?

All of the sudden can't use Hotmail through Firefox I have tried clearing cache, making sure clocks are correct etc.

This is the error page that I get. How can I fix?

Hello

We use ManageEngine's ServiceDesk plus and all has been fine until Firefox 148 update was installed.

The body of a request where we type details of a case or insert images now will not display anything. The data fields are fine, it is just the description box which appears to be iframe. Other browsers still work, but we prefer FF.

Thanks in advance - Terry

Hello everyone,

I keep having the issue that on some websites, a whole list of cross-site cookies is displayed when i click the icon to the left of the address bar. "These parties can use cross-site cookies and site data while you are on this site."

Especially Google (I am not logged into a Google account) lists many different sites here. I can then click on "Allowed X" - but after a few days, the entry appears again without me being asked!

Under "Privacy & Security" I am using the Standard level. It says there: "Firefox blocks the following: (...) Cross-site cookies in all windows (...)" So why are some still being allowed? How can I generally prohibit them except for those I manually allow? The five levels for cookie handling under "Custom" are unfortunately not very self-explanatory, and I can’t find any whitelist option there either.

Thanks for any advice! Best regards, Martin

I am unable to recover the original profile files, and this is not me trying to recover that; they are just gone completely so, I can't bring that original profile back to fix this. I have refreshed, uninstalled, signed out, closed the tabs from my sync list, etc, but I can't get this to go away. I don't know what to do.

I am being locked out of my Firefix desktop linux account using Ubuntu. It had me successfully change my password yesterday and today won't accept any of my known present and previous passwords.

Is anyone monitoring this community? Has it been abandoned?

I've been having an ongoing problem. I fixed it myself, because after posting here, I had zero responses and didn't know what to do, so I messed around and tried things on my own, which seemed to fix it. But apparently, it is not fixed, and I still don't know what to do. A Firefox expert I am not.

Very simply, I use two different computers, each 2000+ miles apart. Each time, and this has worked for well over 3 years now, the entire computer is copied to a backup. The backup data is restored, the current Firefox profile, as well as the Firefox program. To repeat, this has worked for well over 3 years now.

In order to get the extensions working, that requires disabling and then reenabling each one. (Otherwise, Firefox will not access the internet.)

This time, the extensions were disabled and enabled, and everything appeared to be working fine, but nope, not a single extension works. Even choosing a different extension that is normally disabled doesn't work.

I used to use Adaware, which is on the disabled list, so I disabled the non-working Ublock Origin and enabled Adaware, and it doesn't do anything. The ads roam freely all over the page. They pop up and dance around.

Not one extension will work. New, old, enabled, disabled, whatever. Nothing.

Does it bear repeating that I am not a Firefox expert? Without an answer from someone who knows what they're doing, I may as well switch to crap, inferior Edge with the zillions of dancing, pop-up ads. And I hate Edge.

I'm begging for an expert to help here.

Firefox does not react to links.. This has been happening in several web pages. Links that work on Chrome and Safari do not work on Firefox. This is the last example, try to click on the different shoe views on this page: https://www.skechers.com/uno---suited-on-air/183004_NVY.html ...
