Firefox Community Forum

All of a sudden, Firefox for Android has been using about 1GB of data daily. My Data Usage monitor says it is almost all Foreground data.

I barely use Firefox for watching videos or streaming anything, especially when not on WiFi.

I run two extensions — Privacy Badger and uBlock Origin, both of which I would assume should be saving me data by blocking ads and trackers.

Data collection settings are set to Off. Autoplay is blocked for audio and video. Stories (sponsored or not) and sponsored Shortcuts are disabled. Tabs open for 2+ weeks are automatically moved to Inactive.

Why has  << teaseyourmatch.com >> opened its webpage yesterday & for several months while; today it won't load the homepage whatsover? This is an adult dating website from Eurozone w over 125000 users

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

Is there any way I can retrieve my bookmarks from old installation of Firefox? I lost my bookmarks due to fault on my PC. I have a new drive and have reinstalled Firefox on this one. Any advice greatly appreciated. Thanks

Why is Firefox blocking my access to certain form fields such as User ID, Email Address entry and Security question prompts to web accounts I have, such as a Rumpke payment portal? It blockeed my access so I cannot so you now for invalid tries because I could not key into them and locked me out of my account- sorry.

The past few months, I get a periodic issue with Firefox. I've done some searches and looked, but nothing anyone has suggested seems to work. I also run the Chrome browser on this same computer (I have 2 Etsy shops and prefer to stay logged in to both of them, so 2 browsers are a must). NOTE: I've been doing it 'this way' since the early 2010.

This is a new Dell Windows 11 desktop. No issues with the computer. The browser is up to date.

I keep from 3-8 tabs open at a time. My Etsy shop. My email. My shipping supplier. Etc. None of these run a lot of hot graphics or anything. Suddenly, I see 'sparkles (the only way I know to describe it) on some text boxes/etc) then...the address bar starts with the flashing pink/magenta.

Appreciate some help in getting this to stop. Again, doesn't happen on the Chrome browser. Only Firefox. I've used Firefox for a very long time and appreciate it. So I hope that I don't have to go to a different browser.

Thanks in advance. I've attached a photo of what I'm seeing. Note that this vibrates...not static.

Some sites have scrambled text. I've attached two images of what I see when I visit this link: https://criticalrole.fandom.com/wiki/The_Calamity

When I inspect the HTML, the text shows up as it should (unscrambled English). I checked my default language settings and they are set to en-US. I tried disabling extensions one by one but nothing seemed to have an effect. However, a private browsing window didn't have that issue.

Hello, I hope somebody can give me some guidance about two issues that are driving me crazy. To provide some context, I use Firefox to work from home and my primary interest is accessing government and bank sites from my country to fill out tax forms and pay said taxes, therefore the browser built in provisions that deal with web page development, shortcuts, Artificial Intelligence, Social Media are utterly useless to me. The issues are as follow: 1. I regularly access the website of the federal tax authority of my country and local state hundreds of times each day. After a while, normally two months, Firefox starts to behave like a drug addict: It develops a resistance to the security cookies from these sites that worsens over time, until eventually the websites plain out kick me as soon as I log in. The only workaround is to use Privacy Mode or another browser until Firefox starts to behave again. In 2026 this started to happen with the bank website too. 2. After a fit of rage after a failed task I was in the process of attemping to destroy the mouse when reason finally prevailed but not before I got another issue with Firefox: The browser now prints (To PDF and paper) every single item from dropdown menues in webpages that cointan these elements. I already tried re-installing the browser, doing a clear install, erasing cache and cookies, deleting profiles. Thank you for any guidance.

I am a long time Chrome user but decided to give Firefox a try for various reasons. 1 like Firefox's ability to highlight and add text comments to articles and documents. One feature lacking, or maybe it exists but I have not discovered it, would be the ability to copy and save all highlights / commnents in an article / document to subsequently use them as a summary, abstract, or digest of main points To preclude having to re read the entire document again And that's wanting to do so. There is a Chrome extension called Highlighter that Does just that , supports the copy all highlights.

Hello,

I've had this problem with viewing expanded jpg's that up until now, I've been trying to get along with. On the website, milesplit.com, there's an option at the bottom of every picture, it gives the option saying to click here to view a larger version. After I click it, I get a small box saying "You have chosen to open..." and then a big string of letters and numbers for the file name. It continues "which is: application/octet-stream file (156 KB) from: d193frjqb908ar.cloudfront.net" And then asks what Firefox should do with it, either open or save it. From there, I always select Open with and click on Browse. The next screen is long and narrow and at the top it says to Choose Helper App. Then, it gives the application/octet-stream name, which happens to be the same no matter what picture you're looking at, and then it says Send this item to and gives (in my case) 6 apps to readily click on, with Firefox being at the top. As I always want Firefox to open it, I just click OK and then click OK again in the smaller box. And finally, the larger version of the picture is displayed in another tab. Now, I've been using this site on and off for at least 15 years and before a few years ago, I had no problems. So, is this a fixable problem, or do I have to keep on doing what I have been doing?

I use Firefox as my default browser. When I click on a link in my apple mail it doesn't appear but when I right click to check the Firefox icon, it shows that a window should be open (call it mystery window). In the photo it's the "Settings". I cannot seem to access it. (It used to be that if I clicked it, it would open.) If I right click the icon I can open a new Firefox window but the one I originally tried to open still does not appear. That's how I opened this page. If I've opened a new window and I right click and select "Show all Windows" I can see the original window but I still cannot access it. I've tried quitting Firefox and shutting down my computer but when I restart my computer the Firefox icon still shows that the mystery window should be open. Still cannot access it.

This is a fairly new problem that started sometime in the last few months. i have an Apple computer.

Despite trying all available solutions, importing bookmarks from Chrome does not work in this firefox latest version 150.0.1. When importing Bookmarks from Chrome, the Saved Passwords file is fully imported and shows 163 Nos. imported. But on opening Firefox, nothing is there. No folder contains imported bookmaks. Tried importing several times, but to no avail. Uninstalled, restarted PC and reinstalled firefox. But importing Bookmarks and Passwords from Chrome sucks. I am fully aware of the procedure. So no more detailing needed. Using firefox since the last 16 years. But the software makers are simply spoiling a good browser by deliberately creating issues. Tried importing from saved html file of bookmakrs, but that also is not helpful. Why Firefox is deliberately causing such errors with updated versions? Please release next version after thoroughly checkining this importing feature and ensure that it works correctly. I tried uninstalling, restarting the PC and reinstalling with with full offline installer as well as online installer. Nothing helped. Chrome works smoothly. Earlier firefox did not have any such issues. With each update, problems after prblems started creeping in with someone deliberately tweeking the software and spoiling a good browser. Please look into it seriously and provide a solution.

Firefox has been my default browser on Mac IOS for several years. I update Firefox regularly, the last being several days ago. I've recently had problems with Firefox freezing as I sometimes manually log-in to Amazon. All other tabs are affected. I have to quit, reopen.

  It is now affecting my purchases on Amazon.  I'm asked to provide a security code from my bank to complete the purchase. The code is initially accepted, but quickly the purchase is rejected by Amazon. Both Amazon and my bank said that there were no blocks on my account.
  I subsequently went to Safari, where I have no problems whatsoever with Amazon. Amazon has not asked me for a bank code to domplete the purchase.
  I think the problem is in my Settings, but it all looks okay. Cookies are cleared. Suggestions are appreciated. Thanks

No Bookmarks (which are shown as imported from Chrome, almost 163 number of Bookmarks) are visible anywhere in Firefox. They are neither stored in the Bookmarks Tool Bar nor in any folder named Imported from Chrome. This is the situation. Uninstalled Firefox, removed all Folders (including the ones in hidden folders) and cleaned the Registry. Restarted the PC, reinstalled Firefox directly from the firefox site online, tried importing the Bookmarks from Chrome after restarting on installation of Firefox. Saved All passwords from Chrome as a CSV file (a Firefox requirement) and tried importing Bookmarks from Chrome along with the Passwords from the CSV file saved on Desktop. Again, the importing showed 163 Nos. of Bookmarks are imported. But on restarting Firefox, no bookmark could be found. Neither in the Bookmarks toolbar nor in any folder named with any name. My Bookmarks toolbar is checked as Always visible. I DO NOT KNOW WHAT TO DO NOW TO MAKE THE FIREFOX WORK as in the previous version. This kind of an error has crept only after updating Firefox to v150.0.1.

macOS Tahoe; 26.4.1 Firefox 150.0.1

I keep most of my bookmarks under the "Bookmarks Toolbar"; I have quite a few of them.

I've always enjoyed the ease and utility of the "Add Folder..." menu item in "Manage Bookmarks", but now it fails on each and every attempt to add a new folder! For example, if I select a folder under "Bookmarks Toolbar", right click that folder, and select the "Add new folder..." item from the drop-down menu Firefox simply "freezes up" - becomes totally non-responsive (spinning beach ball!).

The only way I've been able to recover is using the macOS "Activity Monitor" to "Force Quit" Firefox! If I repeat the "Add Folder..." process described above - Firefox "freezes up" again. I've tried re-booting, and that doesn't cure the problem.

Without trying to confuse the primary issue, I have noticed other "bad behavior" from Firefox:

1. 1. Firefox "disappears" from the menu bar regularly. I can get it back by moving to another desktop, and returning to the desktop with my Firefox windows. However, it will disappear again in short order.

1. 2. Firefox is very slow loading some of the web pages I visit regularly.

When did this start? It started very recently. I have a new (about two weeks old) MacBook Pro. The "Add Bookmark.." issue began only today, but the other issues I mentioned have been around longer.

This is frustrating... I suspect this is caused by Apple's macOS software, but of course have no way to prove that! And in the "FWIW Column": my Chrome browser has basically the same function and interface for adding folders, and it still functions flawlessly.
