Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

Dear all,

We develop a system on D365 platform. On Chrome enviroment, I click the export option, it will download the excel file, I can open it on Excel. However, I click the export option on FireFox, it will download the excel file but I can't open it on Excel. When I use the notepad to open the file to see the content, I found the file become HTML content. I can see the file on web broswer. I don't know why the file content will be change HTML content when I use the Firefox to download it.

Please help....

I just got a new computer and had my info transferred. It is probably the latest version of Firefox on the new computer now. On the previous version it seems like Favorites was spelled out toward the top of the page on the left hand side. I see now it is just a star icon. Is there any way to get it the way it used to be? I'm sure I will get used to it the new way, but I still liked it the other way. Thanks

I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

Duplicate question, please continue in your 2nd thread: /questions/1445013

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

I just switched to Windows 10 from Windows 7. Firefox was working fine, but now many or most pages are garbled; see screen-capture fragments at http://www.fenichel.net/firefox/. I tried a new Firefox 64-bit, but it crashed on most pages.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

I have two desktop icons for Firefox. Each opens to a different file. How do I clear the old file? What do I do about the message that Firefox can not update automatically? Where do I look to see Firefox file and see what date it is downloaded? If it is operational? Why is the same series of problems repeating daily?

Ever since the update, I have had pink flickers on videos on youtube and twitter. They last for less then a second, so I couldn't grab a screenshot of it. After doing some reading online, I turned off hardware acceleration which turned the pink flicker black and now effects several sections of the web browser.

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

I just added "TextArea" to my extensions & it only can be selected by clicking on the picture puzzle icon at the right edge of the address/search bar for a dropdown box of extensions. I would like to display it and a number of others now only on the dropdown on visible toolbars, but can't move them there. When I select "Customize," it shows some basic icons not being displayed, but only the basics and does not include extensions I've added recently. I used to keep icons in the All-in-One Sidebar on my left margin, the Vertical Toolbar on my right margin & the bottom Status bar in pre-version 57 FF and don't want the extra hassle of having to use the dropdown for commonly used extensions. How do I get these icons moved into an existing visual space on my browser? I have 3 36" HDMI screens & plenty of real estate to play with, but no way to use it in FF for new extensions. Do I have to continue to use alternatives like WaterFox Classic & Pale Moon?

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.
