Firefox Support Forum

Greetings,

Today, I went to access my Bookmarks, & found them "Empty", other wise "Missing"!

I found the "How to recover missing Bookmarks" topics, & that did bring back,what I consider to be My "Permanent Books", bu the section called "Other Bookmarks" will not come back, no matter how many times I go through the "Restore Bookmarks".

I Absolutely need that section to be restored, for I had many files in that section that I updated daily, that I planned to move to the "Bookmarks Section".

How can I get get this section restored?

' bold text' Good Evening,

 I had an update to install on my laptop for Windows 10 and now Firefox does not open. I have tried everything, uninstalling, reinstalling, standing on my head and nothing works. Can you please assist?

Thank you, Christine Gernant

When you open other web browser, it starts with the cursor on the search bar ready to type and search. I wanted to know how I could change it so Firefox does the same.

I downloaded Myki Password Extension. I have the program installed on my computer, but I can't figure out how to get the extension 1) To the main toolbar, and 2) to record my usernames and passwords and 3) Autofill as a result.

I am getting these errors in the browser console. I am using Firefox Developer 87.0b6 I have disabled all telemetry options except for telemetry enables, because that is locked, but I am STILL getting pin errors. https://support.mozilla.org/en-US/questions/1197144 See my about:config settings below. How do I stop this? The errors are particularly annoying because they don't clear when refreshing a page like other errors. Debugging is extremely painful.

The great thing about DNS over HTTPS is that it's done at Application Layer. However, Firefox doesn't leverage this - producing a boilerplate response when DNS response failed.

I'm using NextDNS with P O R N category blocked, with https://dns.nextdns.io/XXXX as my TRR (and network.trr.mode is "3")

When NextDNS does its job and responds with Server failed, Firefox should be able to produce an informative response to the user, rather than "Firefox can’t establish a connection to the server at P O R N .com." which is more about connectivity than DNS failure.

Feature Request: Firefox be more informative DoH DNS failures?

Stretch Feature Request: if network.trr.mode is "2", Firefox passively notifies user that preferred method failed.

New laptop. I believe there are major issues with Windows 10. I've posted them on MS message boards but no one is experiencing them (don't notice? Don't care?). I use Firefox, and while I don't believe Firefox is the problem, I thought I'd post some of them here (the short version).

Links open by themselves without me clicking or tapping on them. When I'm in a Hotmail email or message board compose screen, or a web page with fields to enter personal information, very often when I click to a spot, the screen scrolls up by itself (happens in Chrome too). Sometimes, writing an email, when I click to a spot, the cursor will instead appear a few lines up (not where I clicked). Even if I don't click, the cursor might, all of a sudden, jump somewhere else while I'm typing, or paused typing (even in a Google search field). At times, when I hit the backspace - to remove characters, text - I'm taken back to the previous web page instead. I have seen this complaint when I searched it. But I don't want an Add On that disables the backspace. I just want it to work as it should, not take me back a page.

And no, it's not malware. And I didn't have these issues with my old Windows 8 and 8.1 laptop.

When being prompt for the primary password, I noticed that I can rapidly and endlessly type random combinations and press enter. There seems to never be any delay between wrong entering of passwords. So it seems that even the most primitive application that would try all possible combinations rapidly, will break the password in few hours for the most. This does not even require any knowledge in hacking. Is this correct or am I missing something? If that is the case, then primary password is only worth when keeping the computer unattended for no more than few minutes.

For more than a year, I've been plagued with, "A web page is slowing down your browser."

It appears most often on Facebook and while multiple tabs are loaded, but other websites cause it to happen, as well, even when Facebook isn't loaded at all. The fewest multiple tabs that trigger this behavior is two (2), though it usually rears its head with around seven or more.

It appears whether extensions or plugins are disabled or not.

This never happens with Google Chrome.

I'm using the latest, 64-bit version of Firefox with automatic updates enabled.

This has been happening for more than a year.

Once a page begins to display this, it's done for the day about 80% of the time.

Closing multiple tabs does NOT solve the problem once it occurs.

Closing Firefox entirely (all tabs) does solve the problem, but only for a while.

Choosing Stop It or Wait doesn't seem to solve anything.

I've tried uninstalling and reinstalling Firefox, twice.

OS: Windows 10 64-bit Anti-virus: Bitdefender Total Security for the second half of the year; Norton Security for the first half of the year.

I really wish Mozilla would put some effort into actually FIXING this major problem, as I've reached the point where I'm about to ditch Firefox entirely and go back to using Google Chrome. Judging by what I've found in these forums, it's been around since 2017, and none of the tips given therein have worked.

It's almost as if something in a tab other than the current one is occupying an excessive amount of processor cycles, and instead of managing it properly, Firefox gets hung up trying to

Suspicion: Facebook, possibly YouTube (owned by Google) intentionally "exercises" Firefox browsers in the hopes of getting users to drop it and go back to the far less secure Google Chrome.

Thank you for your time.

Hello, I recently sent my firefox crash report to mozilla including the webpages I was visiting.

My concern is: will be kept the privacy of the page I was visiting? simply because it was my email and linkedin account :)

thanks,

I just updated to a new laptop, and I'm now having a problem with Firefox. I'll be reading a page, when it will suddenly zoom in - the zoom feature stays at 100%, but I have to scroll across the page to get to the end of lines. I can't figure out how to make it go back to normal - I have to close the tab, then open a new tab and open the URL again on that.

What is causing this? Is it a setting I can change? How do I fix it?

Thanks!!!

Whenever I visit Tesco website for online shopping the pages get progressively slower to the point where I get a message in a yellow banner which reads words to the effect of: 'A web page is slowing down your computer. What do you want to do?' It then gives the option of clicking on a tab to either 'stop this' or something else which I no longer recall. This message doesn't stay there long and on the times where I have managed to click on the tab 'stop this' it has no effect whatsoever. I looked up this problem by typing something about it into a google search space and came across information which says that it is an apparently known problem with Firefox. I cannot account for the testament of this answer though. I don't know who wrote it. Is this true? Is there anything I, or you, can do about this problem regardless of whether or not this is true? When this happens my computer sounds like it is about to launch itself into space and there is a distinct and lengthy lag between entering information and the website responding. It can take over a minute to move from one action to the next. eg. scrolling the page up to view the next items on the page. I really would be forever grateful if you could identify the problem and come up with a solution for this. Thank you for giving this your attention. Helen Gray.

Hello!

I’ve been having quite strange problem with Firefox for a few months since version 80.X on clean Windows 10 (reinstalled from scratch after secure erase; the latest 20H2 version with all updates installed). It’s worth to mention that I’ve been using Firefox like 15 years and never had an issue like this before.

Firefox just fills up system drive completely (50+GB to 0 bytes remaining) few times a day under active usage. It happens randomly and I can’t identify the reason. I also can’t find any actual files saved on disk because it seems to be related to NTFS cache. I’ve tried disabling the following settings with no success:

browser.cache.disk.enable cached-web-content_cached-web-content browser.cache.memory.enable browser.cache.disk.smart_size.enabled

And couldn’t find any solution unfortunately. I usually have 2 windows opened ("common" and private) with 10 to 30 tabs each which is not much at all for i7/16GB I believe. This problem is extremely annoying and seriously affects SSD life so I'd really appreciate if someone would help me to resolve it. Thanks in advance!

I can't get Firefox to show the bookmark editor. I thought i may have accidentally manually disabled it for new bookmarks, but when i tried to access it on an existing bookmark, it wouldn't come up. The star button still has an "Edit this bookmark (Ctrl+D)" tooltip, but does nothing when clicked. Ctrl+D does nothing further on an existing bookmark. I went into about:config, and the browser.bookmarks.editDialog.showForNewBookmarks option was set to true. I went ahead and toggled it off and on again to see if it would refresh or something, to no effect. Ultimately, i guess that's beside the point, as i can't even bring it up for existing bookmarks.Any suggestions, beside going in and manually shuffling each new bookmark into a folder from the library?
