Firefox Support Forum

I can't figure out how to delete this extension: Adobe Acrobat. It's disabled, but I want to delete it.

Hi,

For years I have read directions to get my tabs back where is most logical for me, below the Bookmarks Toolbar. Now with this latest version of Firefox the workarounds I had before are not working.

To cut a long story short: I have made a Chrome folder under the Profile folder I have made CSS sheet with what looks like the commands I need. I have configured Firefox to read the userChrome.css sheet.

I have followed all the directions on this thread https://support.mozilla.org/en-US/questions/1375646 (most of which are repeated elsewhere) and it still doesn't work.

I am beyond frustrated - if anyone happens to know where I can go to request this as blinkin' option I would love to know.

Please could someone help me sort this out in the meantime though?

This is what is in the CSS sheet (which is in the correct place according to the above instructions - checked that already):

Thank you in advance.

Hello Mozilla Support Team,

Since one of the last updates firefox Download Setting seems not work properly...

Into Settings > Files and Applications > Downlods > Save files to option is ALWAYS on, even when "Aways ask you where to save files" option box is checked. When I open a PDF in view mode with Firefox, it automatically download it to the location described into "Save Files to"..in my case Desktop. It seems that the "Save Files to" option doesn't gray out when "Always ask..." option box is checked.

Do you have any idea why I can't chose just one of the two options?

Thanks for you help...

Alex

P.S. Attached screenshot...

I was quite unhappy with the new Firefox Proton design, so I made a CSS file and copied the following code from a website. However, I don't know what to do to (1) slightly reduce the tab height, (2) get back tab borders for inactive tabs and (3) remove the small gaps between tabs. How exactly do I have to change the following code to do so (ideally, for convenience, please just complete the code accordingly)? Thanks in advance for any support!

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

Hello!

I have the problem that every of my most visited sites are loading normal fast except for YouTube.

YouTube needs about 2 to 3 seconds to load the site itself and the thumbnails like "lagging" pictures which are rendering real slow while my other most visited sites like Twitch, Reddit or Twitter are loading in about 1 second or less. (i have installed the "Page Load Time" addon to check that).

I have only installed uBlock and nothing else.

When I open Firefox settings I can set; Firefox Home (Default), Custom URLs..., or Blank Page. I altered the Firefox Home to show a custom image per [[How to add image to my firefox home page / newtab page|https://support.mozilla.org/en-US/questions/1288490]] . Now I'd like to show the Firefox Home page every time I open Firefox or open a new blank tab.

When I read the article [[How do I set a different Home page and Home button|https://support.mozilla.org/en-US/questions/1341696]] the options in "about:config > browser.startup.page" are limited to "0-blank; 1-home page; 2-last visited page; 3-restore previous session", but there is no Firefox Home page in this option.

So, it seems I cannot have Firefox open to my custom Firefox Home page (and NewTab) image and have the home button open to my corporate web site. Is there another option that I can accomplish this?

Firefox consumes a lot of processor time in background. How to disable it?

Following options do nothing: Use recommended performance settings - dasabled Use hardware acceleration when available - disabled browser.tabs.remote.autostart = false

I got a new computer running windows 11.

I installed Firefox as my default browser. I then noticed the address bar performing search which is annoying as hell and actually and interferes with productivity as I use search. Basically, I have to redo searches after the address bar. It is problematic. The one off search from address bar according to last survey only 26% of users like it. rest want it gone.

As for me, I have tried the solution of Keyword set to false and the browser url oneoff also set to false.

I saw another suggested item of turn off keyword search. However, that item does not have an off button or switch within Windows 11. Just check marks of the suggested keywords that developers installed into the field when downloaded. I unchecked all the items as that was the only change I could do. So, there is no keyword selected. I closed all browser windows and restarted Firefox.

The address bar search still occurs. This make the previous question and answer solution invalid as of August 12, 2022.

I consider this a BUG and a major development of Firefox browser failure. When I search, I am looking for generally wide range of results and alternative search options are better than specific one off search. Best example; What is difference between Clementines and Mandarins? As a one off search you get one set of results. When you use the proper search box of a search engine, you get totally different results that are more useful and less time consuming to know the full range of answers, history, physical traits as well as other items not considered in the address bar search. In the search engine box, you do get the address bar search items. However, they always are 6 to 20 down the list of preferred or most useful. However, the address bar search results do not have all the top 5 items from the search engine search. It is a matter of how the address bar does the search that is at issue. For whatever reason, the results are not as good as direct input. You will have to determine through investigation why that is. However, that is a year's worth of investigation if anyone would do it. In the mean time, this address bar search needs a simple button that does all the changes necessary to make it stop!

Additionally, I find multiple related search options that are given by search engines extremely helpful when looking for related type of searches. This is something that the address bar search can not do and was never designed or allowed to do. Thus, it causes loss of productivity.

As such and because it does cause loss of productivity, it is a BUG and by law, Mozilla must remove items or provide easy solution to stop productivity failure.

The current solution does not work. That means Mozilla must provide an update immediately to make this feature go away for those who find it annoying, useless or interference with productivity!

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

Hello,

I want to permanently remove these notifications by whatever means necessary.

This is the same issue that was[[ previously discussed here.|https://support.mozilla.org/no/questions/1237229]] previously discussed here. However, the chosen solution is only a temporary workaround, I am only interested in a permanent fix. I have dom.webnotifications.enabled set to false yet these notifications still appear. Is it possible to disable them using a policies.json file?

Hi Firefox Community -

I am using Firefox 115.8.0esr version. I had previous userchrome.css from older versions of firefox from 5 years back which does not work anymore.

Need userchrome.css content for highlighting background color of bookmarks in dropdown.

Can you someone provide me with this userchrome.css snippet to high bookmarks with background color in URL dropdown box?

Thanks - Tarun!!

I have a problem with how firefox is treating link to the file of type ".wotmod". For some reason firefox without asking is just opening file in the active tab (displaying it in the browser) when what I want to do is to download the file. Can i somehow force firefox to let me decide what to do with files of that extension? I did set action for all available ContentTypes to "Always ask" and I did check "Ask whether to open or save files" option in settings, but still Firefox is just opening those files in the browser. Other browsers like Chrome or Edge are letting me download the file, but I would prefer to use firefox for all my browsing needs. For anyone interested [[here|https://gitlab.com/wot-public-mods/replays-manager/-/releases]] is the link to gitlab release page containing multiple links to files of affected type. Below I have added screenshot of my settings: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-06-16-13-10-17-d4c7aa.png

I've downloaded a couple of add-ons this week that did not do what they claim to do, so I wanted to leave reviews so other users won't waste their time. Except when i got to do so, i am surprised to see that therte is no clear way to write a review for an add-on. I am logged into the add-ons page, i can view the previous reviews for the add-on, but nowhere does it inticate how I can leave a review. Google led me to the Mozilla add-ons wiki which states "You can complete most of the review using the reviewer tools at addons.mozilla.org" except there is no indication to where one can locate these "reviewer tools." Seems a bit funny to me that Mozilla would choose to hide the functionality and make it so difficult to use.

Any help is appreciated.

I have the latest FF installed, and have tried to install a couple extensions. Bitwarden and bypass paywalls. They both install ok, show up as enabled on the manage extensions page. But they do not run. They also do not show up with a left click on the extensions icon. BW in particular needs to be accessed to sign in to the pw vault, however, it's icon does not show up on the toolbar (nor does it show up as an option on the customize toolbar menu.) I have deleted the extensions.json file (other files mentioned were not found), but it made no difference. Any ideas?

I can't get Amazon back as a search option Bing is one of the search options selected in search settings, doesn't appear.

If I install an older version will it be ok. Why do they keep installing new updates which cause issues with the one I am using. I installed Opera and will give it a try. Firefox keeps changing things that work.'bold text'

I use Last Pass for passwords & it's worked in the past on Firefox. After updating Firefox, the Last Pass extension in by toolbar is black - in the past I would click that, open the Last Pass page to sign in, then the icon turns red and functions. Now when I click the icon a frozen page comes up that never loads. I can sign in to the Last Pass webpage, but that doesn't turn on the extension.

Any advice appreciated - thanks!

I know Firefox recently changed some settings regarding automatic downloading of files, but I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? Thanks

I'm running Mojave 10.14.6 on a MacMini (late 2018) with 64 GB 2667 MHz DDR4 and Firefox v86.0 64-bit.

I need to disable Command+D that's currently used to "Bookmark This Page".

I need Command+D for another use.

I've searched about:config for "bookmark" and get a lot of hits, but I can't tell which one controls the setting for Command+D.

Or . . . am I barking up the wrong tree?

I want to disable Command+D.

Leaving the ability to mouse up and click Bookmarks > "Bookmark This Page" is ok.

I just need to disable the keyboard shortcut Command+D for "Bookmark This Page".

Anyone got a "howto" for this?

Thanks!
