Diễn đàn hỗ trợ Firefox

I just updated the browser. Just prior to doing that, I used used this website https://www.carpetmdinfo.com/ without any problems. Now, as click on the different tabs of this website (Home, About Us, Our Cleaning Process, etc.), nothing happens. The same website works without problems with Safari.

Does anyone else experience similar problems?

I looked at reporting the problem as a bug, but I am sorry, it is too complicated for me. If someone could replicate the problem and report it, if in fact the same happens to others, I'd appreciate it.

Hi there,

I've got plenty of bookmarks organized in folders and sub-folders (never could wrap my head around using tags). Normally, hovering on top of a folder or sub-folder just opens it. However for some unknown reason, some folders just don't open on hovering. By contrast, opening the "Manage bookmarks" pane shows all bookmarks are there and functional. The issue only appears in the menus, and I'm not sure when it appeared exactly.

Already tried: Renaming faulty folders: no effect Moving bookmarks into a newly created folder: no effect Moving faulty folders into an already-working folder: works, except if the folder is the one containing the root menu.

How to solve this strange issue?

Hi, I just discovered something odd. Trying to troubleshoot something with an android app communicating via web and laptop to free up the phone, and the relevant website has a chat popup and Firefox won't open the popup. I added the website to the whitelist and saved, but still wouldn't. Tried troubleshooting mode, but nothing. Switched to Chrome and it works fine. Cleared cookies and cache and restarted Firefox, but still no luck. The website is ExpressVPN.com. Macbook Pro OS10.14, Firefox up to date, version 115.1.0esr (64-bit).

Hi there,

I just started a seldom-used FF profile to have it synced (you lose FF sync connection if you don't log in within 2 months, I think…). I set up my account for decent security: 2FA, wrote down the recovery key and recovery codes.

As I changed the password recently (didn't re-generate said recovery strings), I expected the disconnected state, all right. So I proceed on entering my new password, and out of curiosity, decide to make as if I didn't have the 2nd factor on hand

The Firefox Sync dialog page now asks me for a "Recovery code" that's 10 digits long. To my great surprise, none of those I saved when first setting up the account worked! I know I didn't use any of them.

More, the terminology had me confused: when is a recovery key used vs. code? Both files contain "Recovery codes" in their name, besides, a "digit" is: "1 any of the numerals from 0 to 9, especially when forming part of a number." Nowhere in Firefox Sync a string of 10 "digits" generated: the "recovery key" is 32 character long, in 8 sets of 4 characters, and the "recovery codes", as I understood it, 10 "character" long (and there are 8 of them), number and letters, so not digits.

Why none of my codes worked? Would have it been necessary to generate a new set after changing password?

Starting last night Firefox will not let me download anything. If I click on a download link, my Mac toolbar goes gray like normal, but no download dialog box ever appears. I have confirmed the dialog box isn't hiding behind any open windows on my desktop, and I have tried rebooting my system with no change.

Please help me fix this.

Hi there,

Firefox is my daily browser and a few websites are causing recurrent issues. Aliexpress randomly switches language and currency, but the most annoying problem is that it doesn't let me change it (clicking on it doesn't give the menu it's supposed to give), and searching any item in the search bar just gives the "spinning star symbol", and nothing else.

Similar issue in eBay: some menus just don't open, including submenus in the "Contact seller" form, which cripples the whole experience.

As a comparison: all these websites work fine in a slightly outdated Safari 14.1.2. and the most recent Vivaldi.

Now, I saw the issue being mentioned here 4 years ago.

What I tried:

1. cookie /cache cleaning, which I did to no avail.
2. Safe mode: no change
3. Switched back privacy settings to "Standard": no change.
4. Manually copied files from one profile folder to another: as could be expected, no change.
5. I even tried a full refresh, but with extensive customization already performed over the years and most of it either in about:config or extensions, I couldn't spend the time re-setting everything back to normal.

FWIW a list of all files and folders shown in my profile folder. I specifically excluded the "known good" files (see step 4). Interestingly, FF also generated an "Invalidprefs.js" file.

After a computer reboot, ALL my bookmarks have disappeared. I'm running Firefox 98.0.2 on Mac 10.14.6 - I've followed all the 'help' advice: I opened firefox profiles, it only shows one. I rebooted Firefox (I was left with bare bones) and still no bookmarks and still only one profile. I've looked in the computer 'library' and I can find nothing compressed (the bookmarkbackups folder has 15 items but all are dated 2022). Can someone please help me retrieve them, I'm in the middle of a project and NEED the bookmarks. Thank you in advance!

OS: Mac OS 10.14.5 Firefox Version: 113.0.2

Settings gives me multiple options for handling a .pdf file. The first three are (1) Open in Firefox; (2) Always ask; and (3) Save File.

If I select "Open in Firefox," the file will open in my existing window. If I select "Save File," the file downloads to my desktop.

The problem arises when I select "Always ask." If I then select "Open in Firefox," the file opens (in a new tab!) and simultaneously downloads to my desktop!

Is this a system glitch, or am I somehow doing something wrong?

Hi everyone,

I have the problem in the Subject line. FF sucks about 500 MB to be run, on top of which it takes 500 MB per tab, and that makes it impossible to run a research on my 8 GB Mac. Yesterday I was looking for a lamp and had no more than 7 tabs open, 3 of which were largely text, 2 were online shops, and 1-2 were websites with pictures. No Facebook or social media, no YouTube. FF froze, made the whole Mac freeze (well, Mac is garbage nowadays but let's leave that out of this topic), and I had to wait MINUTES before I could close it, because the computer was nonreactive.

When I check online, I see people being like "why can't it manage more than 50 tabs?". 50?!?! My computer dies with a maximum of 10 when it's only text websites!

So, I guess there's something wrong with this.

- I don't have many extensions (SimilarWeb, VPN, and Flash Player), I always use incognito so I can't use the plugin that allows me to use several accounts at the same time, so I can't see what's messing with my Mac. - The Activity Monitor (pretty much Task Manager on Windows) shows "FirefoxCP Isolated Web Content" for each tab, could that have anything to do with my problem? - CPU usage is very low, some 0.5 to 10% max during heavy use. - I seem to remember I used to have dozens of tabs open in the past, although I can't be sure. Is this a recent problem?

I really hope there's a way to solve this, because now I always fear that opening FF while on a Zoom meeting might freeze the whole thing.

Thanks to anyone who might want to shed some light on this big problem.

Screenshots: RAM and CPU usage with 2 tabs open. Two, taking more than 1 GB of RAM and about 250 threads in total? While using 0.2% of the CPU? I'm lost

Something changed a couple months ago where Firefox's spell check began only catching about half of my typos. Over the last 15 years I have become used to my browser providing spell checking services, looking for the little red lines to point out my mistakes, so now that this feature has stopped working reliably I am constantly submitting items with embarrassing typos, having to go back and edit almost every single post I make after the fact. Is there any way to get this working properly again? Thanks.

My old 2009 MacBook Pro broke, got fixed, and now the backup won't transfer. So I need a new Firefox.

OS X El Capitan V10.11.6 is the latest this old computer will handle. On the mozilla.org download page, the app on the .dmg that gets downloaded says it wants OS X 10.12 or later.

I'd appreciate your suggestions.

I want to know what caused the Firefox icon to disappear from my dock and be replaced by the generic icon. Firefox seems to continue to work well. I don't want to re-install it when it seems to work. However, I want to know what caused this to happen and if there is an easy way to restore it to the unique icon. I've read about the various remedies but don't want to take the time for a re-install when everything seems to be working.

Please just tell me the cause and if there is an easy solution.

My keeper add-on needs me to enable permissions for a new feature (Access Browser Activity while Navigating), but I can't find anywhere to enable that permission. In my add-on manager page in firefox it lists the Keeper extension, but gives no option to enable the needed permission. Can anyone help me out?

I've used Firefox for years on my iMac with its 5K display. The UI was fine. Today I had to delete and then re-install Firefox because the program had started crashing repeatedly. I lost a lot of bookmarks & tabs. Upon opening the new install, I saw that Firefox now shows a miniaturized UI that is very difficult to read. I refer to the UI elements (tabs, bookmarks bar, URL/search field), not the web pages themselves. As part of the installation, I went through all the settings, and I didn't see any controls for the sizes of UI elements. So I searched the internet and found many reports of similar problems over many years. I tried a few suggested changes to about:config settings. Nothing has worked. I am exasperated. What am I missing? Can anyone help?

What is going on?

Very unhappy with this

I am using a MacBook Pro and latest version of FIrefox 100.0

PLEASE HELP ASAP!!!!!

Hello, some years ago I found how to prevent FF to ask for the master password too often. Obviously, this setting involved the about:config editing. Now, I'd like to reduce this time because I'm requested for the master password only at FF launching and I cannot find the options I changed. I looked for options with the word "expire", but it doesn't seem to affect the situation. What was the option I changed? Or what is it now (in case latest FF versions have different options)? Thanks

Is there a way for the new window animation in Firefox for Mac to be disabled?

Safari does not do this, but firefox has a... ~100ms animation for new windows that's extremely frustrating for those of us who do not use tabs (Apple's Exposé/Mission Control obsoletes them).

I haven't found a configuration in about:config, although I've been able to disable a few others.
