Today I realized that I have installed two (2) versions of Mozilla Firefox on my Laptop PC which I rarely use.

Both editions are 64-bit type but one is version 109.0.1 (11/04/2023) in

C:\Program Files\Mozilla Firefox and the other is version 128.0.3 (28/07/2024) in C:\Program Files (x86)/Mozilla Firefox.

I suppose it is illegal to have two versions of the same App., so the question is how can I delete the old version (109.0.1) without affecting or damaging the new version (128.0.3)?

Thank you, JOHN HATZITOLIOS

How do I get access to a page that is unsafe if I want it. As I do service a lot of old machines and it is anoying that I have to use all the time a different browser because of not getting thrue to the page if it is for example only http:// and has not Cert.

This anoying feature is very bad as it is destroying the usage reason of firefox.

Moz Developers,

I would like to add a default exclude words from from search results. So for example, my search would be

"Best places to live" but I would like to exclude Africa with

"Best places to live -africa"

Could "-africa" be added to a default search bar settings so I don't need to type it?

Cheers

I want to dismiss one shortcut out of the two rows of shortcuts on my homepage. When I left click on the three dots on the Google Translate shortcut, and then left click on dismiss, the shortcut blinks and remains.

I have to search for a lot of entries in a long page, click on them to another window, do something (fill in a syllabus) and then go back to the long page and change the next search hit.

When I return to the long page the search in page is remembering where I am in the number of searches shown at the bottom of the page (e.g. 19/34) but when I click on the down button, instead of going to 20/34 it jumps back to 1/34 so then I have to press the down button 20 times to get to the next search hit.

Is there any way around this, so that I can just jump to the next search hit without having to press the down button 20 times?

I thought it might be the fact that the search is off screen but that is not it. It is the fact that I have left the page so the focus has been forgotten (except as the number 19/34 on the search in page bar at the bottom).

Is this a bug?

I want to programatically access the open tabs #document object by the Browser Console. I am in chrome://browser/content/browser.xhtml I fallow the docs in browser console: https://firefox-source-docs.mozilla.org/devtools-user/browser_console/index.html

Following the code: var newTabBrowser = gBrowser.getBrowserForTab(gBrowser.selectedTab); newTabBrowser.addEventListener("load", function() {

this page has been eaten

}, true); newTabBrowser.contentDocument.location.href = "https://mozilla.org/";

.contentDocument is null except if current tab is a page such as page about:config

Is there a way to allow chrome:// tab to access read only of the tabs #documents property using the console?

I understand that accessing it with javascript from the browser console would be a security issue. I want to bypass it to read, analize and compare dynamic data from the open tabs.

My configuration is the following: Windows 11, internal display connected to iGPU and external UHD display to nvidia-HDMI port, multiple firefox windows are opened (1 one the internal screen, 2 on the external).

Then in Windows->Settings->GPU I can select firefox to run on either iGPU (powersaving) or on Nvidia GPU (max perf), the problem is the following: Whenever I set firefox running on iGPU, there would be a massive stuttering/framedrop on an external display (connected to NVIDIA), while a perfectly smooth browsing on internal display, and vice versa.

My first attempt was to disable webrenderer compositor or switching it to a software rendering, which fixes the heavy stuttering, but the scrolling becomes overall less fluid/responsive.

However, setting "layers.gpu-process.enabled" to "false" seemingly solves this problem completely. Now I have a perfectly smooth scrolling on both displays, regardless of which GPU is used in Windows->Settings->GPU (nvidia's is arguably a little but more responsive).

Hope this helps someone, or maybe dev team could look deeper into this.

Thank you for the great browser!

I would like to be able to quickly identify certain URLs that appear in my Firefox history by simply looking at corresponding icon — is there a way to edit a Firefox history item to do this?

I have Yahoo.com as my email provider (Firefox is my internet provider). When I get emails I don't want, I move them to the Junk Email option BUT, it only deletes that specific email and does NOT keep it from being sent again (and they ARE, repeatedly). I contacted Yahoo and and all they do is send me to a website that will answer the question but sign me up for a monthly $46 to $55 fee. Any way known that I can solve my problem?

Hello, I faced such a problem as a very strong contrast on all videos, for example on Youtube. I used firefox 2 years ago and there was no such problem. I tried to reduce the brightness and contrast in the monitor settings, but alas it did not help. Please help me solve the problem

Is there a way to change text alignment for Firefox PDF viewer?

When I add text to a PDF file, sometimes it's left aligned and sometimes centered, so I think I might have changed the alignment accidentally.

I currently run MS10. I do not like MS software but use its OS. I do not want to use MS11 when MS10 is no longer provided with security upgrades by microsoft. Will Mozilla Firefox browser run without problems on either Linux or ChromeOSFlex? If so, which OS is recommended by this community?
