Firefox Support Forum

hello team,

i have a question about feature in firefox, that is auto sleep tab. that's what i call it.

let me tell you first to get better understanding. so i'm work as a vendor for my client. and to connect to my client environment, usually i used remote desktop connection. there is firefox too but a little bit different. in remote desktop firefox, there is a feature auto sleep tab. so tab that hasn't been accessed in a few minutes will going to sleep state. but it's different with my local firefox. no matter how long I do not open the tab, it never goes to sleep state. i'm pretty sure i'm using latest version and same type of firefox. but why that feature doesn't exist in my firefox?

Long story short I've lost about 30-40 tabs and can't get them back. What happened was that my computer was being strangely slow, so I opened task manager to close some stuff with one of them being firefox. I had about 6 windows open, 2 of them having a lot of tabs, the other 4 only having a few. Reopened firefox, click restore previous session and only 3 windows reopen. I've never had this before and am scrambling to try to fix it as the tabs/windows that did not reopen are the ones that were actually important. I've tried to use the scrounger thing that jscher2000 has suggested and haven't been able to find anything (I don't know much about code tho so could probably be missing something). I don't know what to do and am panicking a little as like I said, those windows that did not reopen were important. I'm trying to figure out if firefox saves older versions of the session restore .jsonlz4 files (besides the .baklz4) but they seem to just be overridden/deleted. Is there anything I can do or am I just screwed? Also recently closed windows and tabs options are empty when looking at the history tab, which has also never happened. New update today so could it be that that has caused this problem? Finally, I've looked at the Import and Backup -> Restore option, which has worked for me once when something similar happened, and between Saturday morning and now (Tuesday), there is nothing, which is odd as I close out all my tabs every night and this morning everything was restored perfectly. Yesterday is when I opened a lot of the important tabs for the one window, so could there be some kind of glitch occuring there? Any help would be appreciated Thanks

Hello,

I would like to set different themes for 2 computers signed into my Firefox Sync account, because I would like Firefox to fit in with each system's theme. Would it be possible to do this? If so, how can I set it up?

Thank you, JetFox

Not noticed before but when I right-click on the Firefox icon in the task bar, it pops up a list of recent browsing addresses, especially the ones that have started off as a i-click, browser tracking or whatever. I didn't think that they should be there as I have selected "always use Private Browsing" and my history is not being saved, or so I thought. These are active links. Clearing history, inc data and cookies doesn't remove these links. Nor does CCleaner or Bitdefender remove these. I want all history and cookies deleted when I exit the Browser. Apart from removing them individually by right-click, what do I do. It seems that Edge does the same on my partners laptop

Dear support, I'd like to ask you about auto-update option enabled in Mozilla Firefox. In our company we have Mozilla Firefox ESR onboarded and in use. One of our security report showed that Firefox version we use across company is vulnerable - because not all machines have the latest version installed. So I was a bit surprised because I know that auto-update is enabled for this application. I've checked it on my machine and I've got the latest version once I open Firefox and check via "About" button, right after that I've got the latest update installed. Together with my colleague we checked it on her machine whether it's really needed to check the version manually and then update is installed or is installed in the background and seems that my colleague got an update without manually checking the version, she just left the app open and after some time we checked the version and it was already updated.

My question is - is it enough to have Firefox open and it installed the latest version in the background without any action needed from user? Or user has to manually check the version and afterwards the update will be installed?

Another question I have, is the application vulnerable even if the app is not open?

Thank you in advance & BR

How can I convert the bookmarks.html into a dropdown/treeview web page? Right now, the exported bookmarks.html is a one page html, which can be a very long list, How can I convert it into a dropdown/treeview html page (or pages) automaticlly? so I can dropdown the sub-tree only when I needed to.

G'day Folks,

I have an issue whereas Firefox 113.0.2 does not display website correctly using Win 8.1e or Win 10 Pro. Firefox 113.0.2 does not display website correctly The site has a Date and Time line with a colour line underneath it, "The current AU EST Date and Time in Tanilba Bay Australia is - June 1st, 2023 2:34:07 PM" "PC-Bug Fixer draws the line" that refuses to show centred.

Google Chrome, Internet Explorer, Bing, etc. all show these items correctly, i.e. centred under the headers above it, but not Firefox 113.0.2.

I have deleted all the History, cache(s), etc., but reloading still fails to show these items as being centred.

Any Ideas please on what I have forgotten to do to fix this anomaly please?

like the title says, i installed the latest Firefox update and my graphics driver started crashing every few minutes. tried updating my graphics card driver (Nvidia RTX3070) and tried to set the browser to software rendering, but nothing helps, it keeps going black and restart every few minutes.

There really should be a option to revert from a update, i had this a lot with Firefox, troubles after updates. And with no way to fix it, so i have to use another browser until it is fixed..kinda troublesome.

There are many mainstream websites that have stopped functioning in firefox that work perfectly fine when switching over to brave and enabling scripts

these are not obscure sites, they are sites for privacy protecting entities hence the lack of function on firefox is perplexing

how do we make these sites work in firefox again to save the switching to brave?

I would like to add the bookmark tree to my Fickle theme so the colors used can also be seen when looking at my bookmarks. I would gladly ask permission from the person who created the bookmark tree extension and try an see if his extensions could list the bookmarks in the same blue/yellow colors of Fickle. I hope it can work and thanks for any and all help. Rob

Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!

Good afternoon,

I've got a problem with add-ons while using Squid MITM Proxy with a custom certificate for Firefox/LibreWolf.

While I'm trying to update / install an extension / theme, it fails with:

``` 1686147276233 addons.xpi WARN Download of https://addons.mozilla.org/firefox/downloads/file/4104397/witchdoctor-2.0.xpi failed: [Exception... "Certificate issuer is not built-in." nsresult: "0x80004004 (NS_ERROR_ABORT)" location: "JS frame :: resource://gre/modules/CertUtils.sys.mjs :: checkCert :: line 177" data: no] Stack trace: checkCert()@resource://gre/modules/CertUtils.sys.mjs:177 onStopRequest()@resource://gre/modules/addons/XPIInstall.jsm:2514 ```

How can I install an add-on while using the MITM proxy?

After I boot my system I am not able to open Firefox as it complains about an open instance. After around half a minute the file disappears on its own.

Deleting the lock file manually works for starting firefox, but seems to sometimes delete my cookies as well.

The issue is not reproducible by just logging out and in again.

Firefox Browser 113.0.2 (64-bit) "Mozilla Firefox for Garuda Linux"

OS: Garuda Linux x86_64 Kernel: 6.3.5-zen1-1-zen DE: Plasma 5.27.5 WM: KWin

I use mozilla on two machines. They both have gotten to where they lock up when trying to access a second page. The normal place they lockup is "waiting nexusensighten.com". I talked with etrade and they had me try MS edge. It works without a problem. I've started having the same problem with yahoo mail.

I deleted cache and cookies numerous time. Etrade guy had me just type etrade.com to get started. It didn't help.

I update automatically. Thanks for your help.

I have been with FF for years now but I started to notice a few months back that sometimes a web site I want to go to would not load with FF - a blank page would come up. Also, that some sites were very slow to load. I would go to EDGE and the sites pop right up with no problems.

Some examples - StartLogic, VERY slow to load on FF. United Health Care - I bring up the site, put my login info in and it brings up a blank page. I go to EDGE with both of these programs and no problems. There are other sites that I have the same problem with.

What's going on with FF? I would like to keep using it but I am finding more and more sites that act like this.

On start up this morning, Firefox was gone from taskbar. I found ff eventually but all my bookmarks and history are gone. Can I recover them? Why did this happen? Also missing home button

Hello - Firefox to Safari bookmark syncing used to work seemlessly between pc and ipad. Noticed it's no longer working. I've done all the resetting/restarting/logging out/uninstalling/reinstalling recommended. It still won't sync. I ended up installing Firefox on the iPad to get the bookmarks from PC. That sync works (takes a while sometimes). But it will not ever update the IOS from the last time it worked (maybe 3 months ago). I can erase IOS bookmarks and reload from iCloud, but the files are months old.

Has this function just been removed?
