Diễn đàn hỗ trợ Firefox

Hello everyone,

I've been using Firefox for quite some time and I always keep a bunch of windows open throughout a few workspaces on my laptop. However, this takes up a lot of resources and looks very messy. So, I've been thinking of writing a script/extension to simply store all the open links in a window to a named list that I can, then, come back to when I need and reopen. That way, I could possibly have different lists, separated by topic and stored in a single place.

I'm sorry if there is an obvious solution for this, I saw a couple of similar questions have been asked before, but none that I could use as reference.

Thank you for your time, have a nice week!

A few weeks ago I saw an Mozilla ad for a new Mozilla software product that cleaned up your PC and made it run better. The price was around $125.00 (I don't remember that exact price). It said that I would receive an email from Mozilla with download instructions. it's been a few weeks and I have not gotten any email. Does anyone know if Mozilla offers any such software or did I get scammed? I'm pretty good about seeing scams but Ive used Firefox and Mozilla for years and trust them. Maybe that's why I wasn't as careful as I should have been.

Thanks for any help that you can provide. Ron

I have just installed firefox on my new computer. I had firefox on my old computer and laptop that are both still running. It has pulled in a list of mostly obsolete accounts and passwords which are listed when I select "passwords" I did not ask firefox to do this. why has it done this. what else may it have done that I don't know about

Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

Good day, The issues that I am encountering are explained below. The solution found after hours of research is uBlock Origin : https://ublockorigin.com/. Do you know which filters and rules should be applied to exclude the Wikimedia Foundation and all of its derivatives from the results provided by my search engine? Please share your knowledge. Sincerely. ________________________________________________________________________________________________________________________ I am utilizing Firefox ESR 128.10 desktop version on the Linux operating system. I wish to conduct research on the internet, utilizing the Startpage search engine. I would like to exclude the following sites from my search results: wikipedia.org, the Wikimedia Foundation, and any affiliated websites, regardless of the language or location settings configured.

What is the correct approach to establish a customized Startpage search profile excluding all Wikimedia Foundation sites? What is the proper setting to create a persistent and customized search engine configuration that excludes all Wikimedia Foundation domains even after an operating system update or reinstallation? Is it permitted to manually manage a customized search engine?

I have been advised to utilize an add-on or create a dedicated profile.

What would be the most suitable solution in my case, and the one that will be the most effective and stable ?

It is unfortunate that mozilla-firefox does not appear to offer a 'blacklist' or exclusion list feature, as that would be the most direct approach to excluding the Wikimedia Foundation websites from the search results.

I thank you kindly for all of your suggestions and responses to come. ______________________________________________________________________________________________________________________

I would like to know what happened to all of my bookmarks I had when I opened my firefox, nothing is there and I can't seem to find out how to restore them.. what ever you have done to firefox, mozilla I hate to say I don't like it at all.. thanks

Hello, I am still using windows 8.1 64bit & refuse windows 10, due to high risk privacy, yes predictable hollow words are said, BUT is Microsoft, a greedy un-scrupled money making, money hungry corporate entity, wants us to willing give it our private details voluntarily or under thin layer of extortion.

Hence my sticking to windows 8.1 as I have certain control, mainly updates.

Will Mozilla browsers be specifically supporting older operating systems like windows 8.1 into the coming years, not just months, e.g. until January 2023

Yes is a blunt question, but is eluded against in other responses, maybe is Microsoft buy out to sacrifice mozilla loyal users or similar, same query is for Brave browser. Mozilla I think is last Bastian for decency & morality, a leader in justice & honour.

I updated firefox, and all my addons and sign ins are gone now. Search history and tabs remained intact. It also created a folder on my desktop, but I'm not sure how do I "extract" my old data from it.

i attached a pic when i put my curser on the firefox icon in my task bar.... i changed my device while ago... previous device show windows not the all tabs... can i fix it... i searched everywhr in settings but i couldnt find any thing related to it....

Hello, Login into my firefox account works on Android but, with the same username and password, fails on Windows 11 with the error message " Something went wrong..." I would appreciate getting your help to fix this issue. Thank you and regards.

This problem just began today on my Win 11 laptop. Firefox is current - 139.0.4. Win 11 is current. No new software has been installed. Firefox hangs up and will not move. Task manager shows FF is consuming more than 90% of my 16GB memory. I must end the FF task to get up and running again.

I recently needed to reinstall Firefox to attempt to deal with an issue. It turned out Firefox was not the cause but when the new browser opened, it did not have the Home icon on the toolbar.

I went to "Customize toolbar" and added it but now it shows up on the far right end of the toolbar. It used to be to the left of the URL area. I tried to grab it with the mouse and drag it but it won't move.

Every time I need to jump to a home page I end up going where it used to be. I realize this is small potatoes but is there any way to get it back where it used to be?

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

Sehr geehrtes Team, ich wurde aufgefordert, ein Upload zu starten bei Firefox. Das habe ich versucht. Ich erhalte die Meldung 'Couldn't load XPCOM' Was muss ich tun, um Firefox wieder zu starten ?? Wird dringend wg. Kontoprüfungen benötigt ! Kann dieses evtl. an fehlender Kapazität liegen ? Z.Zt. habe ich 371 MB von 111 KB zur Verfügung. Ich bitte Sie, mir schnell zu helfen - Danke vielmals. MfG Karin Gähler Telefon +49 [phone number removed]

recently, if i attempt to bookmark a URL, the dialog box to choose which folder to save to no long appears....the bookmark is automatically saved to the last folder used. i discovered that i can copy the url, open manage bookmarks, and paste into the desired folder...however.... I would like to change this back to allow me to choose from that dialog box. any assistance is greatly appreciated. thank you

Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don
