After I upgraded to Ventura 13.1 on my Mac I noticed the text on some webpages was not displaying properly. I checked to see if there was an upgrade for Firefox and there was so I installed it. Last night after that Firefox upgrade the text displayed correctly. Today the problem is back. I am attaching a couple of screen captures to illustrate the problem. Thanks for your help!

Hello all, First of all thank you for the good quality of mozilla products. I am using mainly firefix and thunderbird on linux (Ubuntu) on all my computers, that of my children and of any friend I can convert to open-source computing.

I have done all possible documented actions to configure firefox for blocking pop-ups, including standard (permissions in privacy & security settings) and advanced (filter on autoplay parameters in about:config) options available. I keep receiving pop-up windows with unwanted videos, e.g. on my paid subscription to a local news website. See the attached screen capture, where I right-clicked on the pop-up window. You will see that a "digiteka" player keeps appearing and I never sollicited these videos. I hate this. It's not even pub, it's news, but when I'm reading an article I don't want to be bothered with other news that I'm not interested in. Plus, I don't want any unauthorised software like this digiteka player running on my computer without my permission. It's not a firefox module, it's probably silently downloaded over my connection with my news provider with no notice. I could go as far as blocking autoplay so the video will not start playing automatically, but I would like to completely block the apperance of such windows and any download of something executable on my computer. What could I do in addition? I there any way, other than stopping my subscription to this site?

Many thanks for your help. Patrice.

You can see from the first image that I had unchecked the "Block pop-up windows". But then if a page wants to pop up the windows like running "for(let i = 0; i < 24; i++) window.open("about:blank")", the result will be the second image. Firefox still keeps blocking despite my setting. And there is no even option like "allow the pop-ups" in the Options menus on the info bar.

I installed version 108.0.2 on my Windows 10 laptop and now my address bar are on the right side of my screen and the bookmarks are taking up the left side. There seems to be no preference to drag the address bar where I want to position it to where I was used to seeing it in the previous version.

Please let me know what I need to do to be able to customize positioning of the bookmarks and the address bar (I combined the address bar/search bar in preferences Settings under about:preferences#search.

Thanks for your help.

I have a MacBook Pro and an Epson ET-3850 printer. I can not get my printer to do two sided printing using firefox but it does work if I use Safari. How can I get two sided printing using firefox?

Thanks ... Jan

Firefox keeps loading incorrect webpages for two websites. The websites are; https://www.diy.com https://www.trade-point.com The two websites work fine with Microsoft Edge but not with Firefox. See attached images. Please advise how to resolve this issue. Thnak you, Mark

Hello, I was wondering if there is any way for firefox to not open a new window when i click a link? Instead, it would open a new tab, not a new window.

if there is any way to do this, please tell me

also, how do you make your bookmarks show while in a site?

thanks guys!

As of recent I've been having troubles with my Firefox browser. Out of nowhere it has started relentlessly purging my browser history to the point where nothing lasts more than a week now before getting deleted, and it is only getting worse. Prior to this Firefox would save data from over a year and simply just remove the oldest data in order to make room for the newest whenever necessary. That is no longer the case now.

I'm fairly certain that I haven't done anything to cause Firefox to do this, but I can't be sure. Looked in the settings and can't see anything that would cause this.

So my questions are: 1.) Can the history deleted be recovered? and 2.) Is it possible to get Firefox to stop purging my history on it's own so frequently?

Any and all help is appreciated.

I recently replaced most of my Firefox Homepage Site Icons with custom icons. (No easy task... loking at you Mozilla)... :)

Now that I have them replaced, whenever I start Firefox the custom site icons take a long time to load.

The previous default site icons appeared to be cached and I was hoping I could force my custom site icons to cache locally to improve loading times.

I can't save an image with an asterisk in the filename when saving from my Firefox browser. I used to be able to, but now any asterisk I add to the filename just vanishes like I didn't type it at all. I can change the file name in other ways, like adding words. I can still save from Chrome, so it's a Firefox issue, and a recent update. Help!!!

Tabs, history, bookmarks, basicly anything and everything that was crucial are gone, seemingly after recent update. I had similar problem a couple of month ago and didn't find clear solution back then, but it all got sorted out maybe in couple of days (probably with next update or something?). Well who would've thought i would get screwed like that a second time.

So i can't tell for sure whats caused it or how it got fixed. What i manged to figure out both times this happend is that somehow i have 2 versions of Firefox Profiles judgin by the dates of the cursed updates. So i guess my stuff is still there but i can't acces it.

Also worth mentioning is that both times i've got screwed by updates, my FF shortcuts from Quick Acces pannel stoped working and i needed to drag'n'drop em all over again.

Im at totall loss here, i know the info i've provided is almost nonexistant but if anyone knows whats up i would be greatly apreciative if you could tell how do i fix this and prevent it from happening in the future.

This all started when I got an email that was captioned: New sign in to Firefox Monitor.

Looking around I noticed that Firefox thought I was using Windows 10 instead of 11.

Hi Firefox community, I don't want to store any account login data (also not usernames) on the shared PC that I'm using. In settings > passwords there is no entry, and under access data and passwords any options are deactivated. Although passwords are not stored, Firefox shows the user names/account names whenever I click such field. Where can I deactivate that user names/account names are stored and shown? Many Thanks in advance. Best wishes!

Terry, thanks for writing me but I even have problems when I only use a couple tabs and I rarely use Facebook or Reddit. Yet even with limited use of Firefox it inevitably expands and expands using up more and more memory until I have to exit Firefox. Is there anything I can do to limit Firefox?

When I bookmark something, I often apply tags. I have noticed that when I use a very long tag, combined with many tags, it prevents tags being used. For example, the word "internationalization" prevents tags being stored.

A bookmark that is tagged like this: one two three four five six seven eight nine ten eleven twelve thirteen fourteen internationalization will not have its tags saved.

However, this is stored successfully: one two three four five six seven eight nine ten eleven twelve thirteen internationalization

This also stores successfully: 'one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen'

Firefox hangs for 5 seconds between every type of download between the "Ok" of the "Save As.." dialog and the actual download of the file.

Any ideas how to resolve the issue or troubleshooting tips?

I'm currently using Firefox 108.0.2 (64-bit) on Windows 10 Pro 22H2

Thanks!
