I have been trying to print the webpage as PDF. I am trying to change the page height and width, but this code is not working. When I manually enter the value of print.print_paper_width and save in about:config it works. Can someone tell me whats wrong. This is what I am trying:

from selenium.webdriver.firefox.options import Options as FirefoxOptions from selenium import webdriver options = FirefoxOptions() options.add_argument("--headless") FFprofile = webdriver.FirefoxProfile() FFprofile.set_preference('print.always_print_silent', True) FFprofile.set_preference('print.print_to_file', True)

FFprofile.set_preference('print.print_paper_width', '3.7')

FFprofile.set_preference('print.print_to_filename', 'filepath')

driver = webdriver.Firefox(FFprofile,options=options) driver.get('filepath') driver.execute_script("window.print()")

After a recent Firefox update, I now get an annoying Firefox pop-up/screen message every time I adjust the volume on my laptop. This appears in the top left corner of my screen, blocking whatever is on there. How do I disable this so it does not happen please?

Hello, I am new to firefox. so, when i install an addons they doesnt show up in the toolbar. how can i add those addons to the toolbar. this might be a silly question but please do help me.

This happens to me and many other people all the time. It always happens with .swf files since I can remember, for security reasons. But it also very often started happening with .pdf files and other file types. Now it happens with .txt files and it's the straw that breaks the camel's back. Inconsistently so as well since when I open it from the website it prompts to download and not when I open the file locally.

This is such a problem that this add-on had to be made https://addons.mozilla.org/en-US/firefox/addon/open-in-browser/?utm_content=addons-manager-reviews-link&utm_medium=firefox-browser&utm_source=firefox-browser And as you can see it is rather popular. Shouldn't Firefox solve this bug (no it's not a feature or quirk) once and for all?

How can I do the same without an add-on?

Hello, i trying actually to create an add on for firefox (for my personnal using for the moment), my idea is : An Lo-Fi radio addon who plays in the background the sound of a live youtube lofi, so I made sure that when I click on the extension it opens an html file containing the live video, my problem is that : if I close the addon, or I change tab, the sound stops, how to make so that the sound plays continuously without having to keep the extension "open", to summarize I try to achieve a result similar to the extension "Nook ", I send screenshots of my code below

The good old option that existed in the Settings to turn off images doesn't seem to exist anymore. I used it occasionally to speed-up page loading when my network is slow and it really worked. Even Chrome, Brave and Edge are still providing that option. Really sad to see Firefox doing this.

PS: I know it still can be changed inside about:config. But that isn't convenient and can't be done for per-site basis.

Whenever I do a general search on the internet most websites I get are Spanish ones. How/where do I change that so I only get English-language websites? My version of Firefox is 81.0.2 (64-bits). I reside in Spain.

Had a problem with an add-on that resulted in all add-ons being deleted. As I wasn't sure what caused the problem, I deleted Firefox and reinstalled it. After the reinstall no add-ons were present. I added back 1 that I could remember, but the second one is gone. I do not remember the name of the add-on but found it very useful in managing pop-ups, videos automatically playing, etc. Would really like to get it back. By any chance, does Firefox store add-on information so that I might be able to find the missing add-on?

I have a file called mozilla firefox backup preferences and in the rar file there is a srtt10ca.default folder. then when you open the folder there are several folders, be it bookmark backup, lwtheme to other files. my question is how to integrate the srtt10ca.default folder into my latest firefox? Please help.

I am using Firefox 81.0.2 (64 bit) on a Windows 10 computer. A couple days ago, my address bar started showing up as yellow with grey text. (Admittedly, I was in the options before that and likely did it to myself). But now I can not read what is in the URL/Address bar without highlighting everything. I have been looking ever since then to somehow reset it back to it's default view, but can't seem to find where to do that. Any help would be GREATLY appreciated.

Thank you

Hi, I use Firefox and Google as my default search engine on Windows 8.1 Each das when I start my browser the search engine in it is Yahoo; however when I go into the settings Google is my deafault which I like to use. When I start in safe mode I am back on google however it is frustrating that I have to restart my browser each day. Could anyone advise please what options would I have to have Google remaining? Many thanks!

Don't you think that if browsers rehabilitate a native "RSS one click subscribe" feature, with better UX (RSS actions/reader nicely integrated to the browser) it could revolutionize the way we subscribe to content updates, removing the need to rely on emails/newsletters in a lot of cases (then being more eco-friendly)? Users would receive content updates notifications directly in the browser, their feeds being synchronized through their browser account, etc.

Web developpers would just have to place subscription buttons: <input type="subscribe">

And a W3C Standard would unify how browsers should implement the "Subscription" feature, focusing on UX (I feel this is the point influencing usage data for the most part, RSS still being a tech-savvy thing).

Feeds handling was removed in 2018 in Firefox.
