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.

ie every time I closed it it would reopen- 14 times when I am trying to read my emails yesterday and 6 today. but I thought it was my internet security causing the problem. I kept getting notification that a certain site was attempting to use my system,. The worst thing was it kept flashing on my screen and wouldn't go away, There was no clue who öwned it, my security or Mozilla's. It was finally resolved by contacting my computer guy, but we never identified the source. the site that was being blocked started with pssst.........com, or something similar but it was driving me mad trying to get it off the screen. If this happens again, how do I get rid or stop the continual notifications? Of course I have nothing to show you as I have since deleted it, sorry. as I was just relieved to see it gone.

Thank you Angela Johnson

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.

Amazon Facebook Ebay National Lottery and others just refuse to load.I tried troubleshooting mode,it worked once and now it doesn't.I believe I'm not the only one with this prob. Help? Thanks.

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit

Over the past few weeks, my typing is continually being interrupted. It did this a few years back, but this is getting very annoying and I am soon to switch browsers if not fixed. BTW on any machine using Firefox, this is happening

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!

EDIT: I found this, may is something similar: https://connect.mozilla.org/t5/ideas/send-tabs-log/idi-p/15640

I recently bought a new laptop running on Windows 11 Pro. All my settings for languages (English GB) in Firefox are the same as my old laptop, which was Windows 10.

On my W11Pro laptop, the translation icon doesn't appear when I highlight a portion of text in a foreign language, whereas it did appear in my old laptop. If I right click on the highlighted text I can access "translate selected text" but nothing happens when I click on that. Translating an entire webpage works fine, it's just the highlighted text that doesn't.

I'm not very technically minded, so any answer will need to be in simple terms! Thanks.

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

About a week ago I had printed 2 copies from my Firefox browser. Next time I only needed 1 and changed it. Since then it stays at 2 and no matter what I do it won't go back to one.

How do I fix this?

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.

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.

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?

How can I resolve the failure to open because it can't find the XPCOM. I downloaded a new copy but the computer insists on using the older, faulty version to open files and it will not work.

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

When I click Bookmarks > Manage Bookmarks I'm taken to Other Bookmarks where I never store anything. I'd delete it if I could but it doesn't appear to be an option, so instead I'd like to taken directly to Bookmarks Menu. I came across this post from just over 4 years ago which sounded like it's exactly what I want, but it doesn't work. Are there any changes anyone can suggest that would allow it to work in 2026?

You can use the autoconfig.cfg file in the Firefox installation folder to initialize (set/lock) preferences and run privileged JavaScript code. In this case code to open the Library with the Bookmarks Menu folder selected. You can modify the showPlaces variable to open any of the four possible root folders (in this case [1]).

To use Autoconfig, place two files into the Firefox installation directory.

   on Windows and Linux, they go into the same directory where Firefox is installed
   on macOS, they go into the Contents/Resources directory of the Firefox.app 

The autoconfig.js file that specifies to use autoconfig.cfg is placed into the "defaults\pref" directory where the channel-prefs.js file is located.

The autoconfig.cfg file is placed at the top level of the Firefox directory.

   autoconfig.cfg and autoconfig.js need to start with a comment line (//)
   autoconfig.js needs to use Unix line endings (LF instead of CR/LF)

} catch(e) {Cu.reportError(e);}

I am sometimes able to open E-Bay, and open individual members of a folder containing over 100 members searches. When opening all the members of this folder, either most of the members will open the E-Bay page with the rest giving the msg below, or all the members of the folder will open, but when pressing the link this msg occurs: Access Denied You don't have permission to access "http://www.ebay.com/sch/i.html?" on this server.
