Firefox Community Forum

Today, I once again had to refresh Firefox Due to my eBay page being rehashed and not usable, but I forgot about my Facebook and after the refresh found I have now lost almost six months of chat history (most recent of which is very important to me), and I just can;t find a way to recover it. Please advise me what to do. Kind regards

Can you help providing a sync from the last 30days. Using a backup computer as my current computer is being repaired and bookmarks/passwords will no sync on this machine

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

Hello Community

Can anyone help me.

After using clean my Mac, I accidently deleted Firefox and important bookmarks. I have searching for the boikmarks folder in TimeMachine but cant find them. Any ideas please?

Best regards, Graham

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 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.

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 ...

I can not figure out how to add a site to allow the location there is no i in the address bar but the site is all about location and I figured I not get a verification email to join the site since it is not on location so how do I add a site with no i site is called nextdoor.com

New OS LMDE7 (trixie debian 13 base) Installed Firefox from the Mozilla Firefox Debian Package mozilla-debian- 1.0 Firefox 148.0

I've just installed LMDE7 alongside LMDE6 and want to move the 6 profile into 7. I've exported the 6 profile into backup and then moved it into the new Firefox Home folder (\home\...\.config\mozilla\firefox) Found both profile.in and installs.ini there AND many different profiles. (I had tried to use the profile manager and seem to have created lots of profiles beside the default-release from 7. Installs.ini shows both the original profile from the 7 install and one created with the Profile Manager and both are locked. They are also in profile.ini as installed.

So my Question is how do I install the old profile into profile.ini?

I am looking to Restore yesterday Firefox have lost all my pin tabs when I opened this morning the browser how can I get my old stuff back? Please help me out. Thanks

I'm away at another location for a few months out of the year. The computer in the other location is almost identical to this one, done in a very simple manner, by using a backup and then reinstalling everything from previous computer to current, most of which is data.

The Firefox profile is copied over and then the version of the program from that other computer is copied, so the profile and program match. The last step is to disable each add-on individually, then to immediately enable them again. (Otherwise, the browser won't connect to the internet.)

I followed the same procedure today as every single time. But then I noticed the blank new tab add-on isn't working. And upon looking at the add-ons...none of the enabled ones are listed (or working). Only the disabled and recommended ones. I don't even know which were installed, and would have a hell of a time figuring out which ones are supposed to be there, and how they're set up.

Where did they go, and how can they be reinstated?

This has never happened before, and I've been doing this same thing for at least 3 years.

Thanks in advance.
