Bookmark manager is quite good - the manual organization is simple, but I'm confused in same case over and over...

I'm pretty sure, I have some bookmarks already saved to somewhere. But I have a lot of bookmarks. And yes, I can search for some bookmark - the manager find them - I can click and all is running, but - where is the bookmark hidden ? In which folder ? Next time I want to go to bookmarks menu and select that bookmark directly... Not calling BM again and again...

This simple information is missing in searched bookmark, when clicked on them once.

It shows: - name - address - tags - keywords

BUT NOT WHERE IT IS... (?) The folder where it stays...

Do You think it is not important ? For Me sure...

Or I have overlooked something ? Maybe ?

Thank You.

There appears to be a bug in Firefox when I use this website, https://www.ourguide.com.au/tv_guide.php?r=melbourne&w=now

When you scroll down, the headings move right and show above the wrong information, see attached screen shots.

If you use this website on Chrome, you don't get the scroll issue so I think it is either a Firefox bug or something that needs changing in my Firefox settings.

I am running Firefox 77.0.1 (64-bit).

Any help would be appreciated, thanks.

I am IT techie, and I need FF help on this. I searched the entire sync issue forum, but of no avail.

I had a Windows 10 update issue so I decided to format my PC. My sync was enabled and all data was synced normally. I went ahead and formatted it, and installed a new copy of Win 10, and all softwares, including FF. Now after syncing for over an hour, I cannot find anything. No history, no bookmarks, no logins, nothing.

This is definitely something to do with your update. I cannot figure anything else out. How can I get my old data back? This is absolutely ridiculous and frustrating.

I have 2 other laptops with FF synced, but they aren't booting up either because of hardware failures. I cannot risk turning them back on, and loosing my FF data from those laptops.

Please advise, how to access my cloud data on FF, or should I switch over to Google chrome because of your incompetency?

Up until recently I was using a 11 year old laptop that was slowing dying. I was finally able to acquire a new computer and get it up and running just before an accident (as if out of a comedy movie - the roommate's cat knocked a full bowl of cereal onto the old laptop) effectively destroyed the old machine. Thankfully, Firefox Sync meant that everything I had been working on appeared when I got the new machine fully functional...until I logged on to Firefox this evening to find my Synced Tabs empty with just a "Want to see your tabs from other devices here? Connect Another Device" message.

The old device is toast...I don't know if it will even turn on again, much less function enough to sign into Firefox. Synced Tabs was also working just fine for a solid week until it just up and disappeared. Is there some way to restore these? I know it's my fault for relying/expecting Sync to always be there and not backing up the links I had open immediately, and this is a mistake I won't make again...but I'd really love to not lose everything I had open.

Thank you very much in advance for any help or suggestions.

Prior to the latest version, I had set "media.autoplay.enabled.user-gestures-needed" in about:config to False in addition to blocking both audio and video within the settings so that nothing would autoplay without my input.

I updated to version 78 yesterday, and it seems that "media.autoplay.enabled.user-gestures-needed" is now gone from within about:config. I'm getting videos autoplaying within sites like YouTube, despite me setting both audio and video to not autoplay.

Is there anything I can do to ensure that nothing starts playing without me allowing it?

Firefox 78 sometimes fails to block autoplay, e.g. scrolling the front page of reddit.com or a subreddit will intermittently show videos playing.

This worked in 77. Some about:config entries I'd swear were set in 77 have vanished; I tried adding them manually, but the autoplay blocking is still hit and miss.

Also, not sure if Troubleshooting Information uploaded successfully or the page broke (see screenshot).

Previously I used: browser.urlbar.maxRichResults, but that doesn't seem to do anything after this recent update. I have to visit a lot of different sites for my job and a longer list in the address bar drop down makes that happen very quickly. Being limited to only 7 is going to severely cut down on my efficiency.

cannot log in to my Bank of Montreal online banking!!!

I've used Firefox for years, and for years I daily do my online banking.

Now all of a sudden, without any warning I cannot log into my bank account. I've tried clearing history, etc. I've tried the about:config change...

I can log in fine with Microsoft Edge.

My wife uses Firefox and she can log into the bank. I suspect that is because Firefox has not updated on her computer.

This is maddening, to put it mildly.

Hello Community

Do hope someone can help?

Have tried all suggestions in Support area on topic: Lost/Recover Bookmarks. Also spoke to Windows Support and was told to call Mozilla Firefox Technical Support. I've been unable to find a number.

I had a Windows update around the same time as a Firefox update, May/June, only realised all saved bookmarks prior to June 2020 have disappeared. This has never happened before.

Urgently need to find out if there's a method of retrievel or have it confirmed that all of these very important bookmarks are permanently lost.

Thank you in advance

The control page of my locally connected printer at 192.168.1.5 is being blocked as a "dangerous" site because it doesn't have a valid certificate as a web site. It's literally RIGHT NEXT TO MY COMPUTER! No path to the public internet is involved! How can I make this an exception (i.e. a "trusted site") to the certificate error blocking routine? I don't want to drop certificate checking for OUTSIDE web pages, just the one that controls my printer (the same IP address is accessible for printing and scanning, but not for editing my printer's options).

The frame for the printer's home page displays but with no data, and no data is displayed when anything is clicked. I've tried to add a screen shot but it doesn't upload.

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

  • This happens for any filetype, from any source.
  • It started happening about a month ago.
  • Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
  • If it's a small file and I try repeatedly, it sometimes will eventually download.
  • Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
  • I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

  • Used Refresh Firefox
  • Cleared download history
  • Changed download location
  • Reset browser.download values
  • Disabled firewalls and antivirus/spyware
  • Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
  • Cleared cookies and cache
  • Ran in safe mode
  • Verified Temp folder filepath was valid
  • Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
  • Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

  • I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
  • Verified places.sqlite was not set to read-only
  • Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!

I'm using Firefox 78.0.2 and i keep getting notices to upgrade. But the last time I upgraded, Firefox changed the locations of my tabs from below the address bar to above the address bar and also changed the behavior of the address bar. It took me a couple of weeks to find the answers and get things back the way they were. I don't want to upgrade Firefox because I have no idea what it might change this time. Is there a way to keep Firefox from sending me upgrade notices when I don't want them?

Hello, Firefox seems to be using my system's High Contrast text color to render websites. My High Contrast text color is a light grey, to contrast with a dark system background. However, many webpages on the internet have light backgrounds, so when Firefox uses this color, I can't read the text. I already have Options>Language and Appearance>Colors>Override the colors specified by the page set to "Never." This also occurs in a brand new profile with 0 extensions or addons in Safe Mode. I just want Firefox to display webpages "normally", i.e. with black text, without regard to the current system colors.

To reproduce: - Turn on High Contrast - Visit a site such as http://hyperphysics.phy-astr.gsu.edu/hbase/ppois.html - Change system High Contrast text color to any color you wish - Notice that the text on the page also changes to the same color, even with the setting on "Never"

Is there any way I can get Firefox to ignore the system's text color settings? Chrome renders the webpage just fine with black text.
