Q: Does anyone know if Firefox has maybe re-instated pinch zoom functionality for Mac users?

Or if there is a decent work around available yet?

And if not, anyone have a good answer as to why Firefox overlooked it in their last major update? Seems rather shortsighted to me. Not being able to pinch zoom on my mac trackpad is highly frustrating. It's pretty much a deal breaker, making me want to migrate back to Chrome or elsewhere. Which is sad, because I thought I'd finally escaped Google for browsing.

On FF v78.0.2 (Win 10/64-bit), it used to be that I could open PDF links within a website using FF's built-in PDF Viewer. However, after saving them to disk, when I opened the PDF from the Downloads panel, it would open in my preferred 3rd party app. This was desired and worked perfectly.

But this seems to have changed! I either have to commit to the built-in always, or an external app always, irrespective of whether I am opening from a browser link or the download panel.

This is a terrible behavior. FF should open PDFs in the download handler (like ALL other file types there) with the OS's preferred PDF handler, which, in my case, is not FF's built-in Viewer.

If open a PDF in the built-in Viewer and save it from there, why would I want to re-open it in the built-in PDF viewer when opening from the download panel?

FF's built-in Viewer is great for a quick view of a PDF, I quite like it. But if I take the time to save it, I typically want more advanced functionality, like highlighting, filling in forms, etc. It worked perfectly before, please revert and stop fixing things that aren't broken. Or at least differentiate between the download panel and website links. Is there any hope in submitting a bug report?

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!

Starting from the last week (as far as I can tell), the uBlock popup is not displaying anything on nightly (works fine on stable). Sometimes it displays the content before quickly going back to a blank state, but I have not been able to find out why.

Hi there My start up page jhas been hijacked by v9-ap.com and keeps on showing a page for a turkish site 'Lider Haber'

I have tried refreshing, using adaware and all sorts of anti virus

Mozilla cfg is // lockPref("browser.startup.page", 1); lockPref("browser.startup.homepage", "http://v9-ap.com?s=92663E31&p=54484550555A5A4C4559532D5043&g=5406EFB439567CFB70247BF3C02E9A31"); lockPref("pref.browser.homepage.disable_button.current_page", true); lockPref("pref.browser.homepage.disable_button.restore_default", true); lockPref("pref.browser.homepage.disable_button.bookmark_page", true);

Any ideas? I have even uninstalled and re-installed

Here's the issue in a nutshell:

When I navigate to this URL (https://publicdelivery.b-cdn.net/wp-content/uploads/2015/12/Jeff-Koons-Michael-Jackson-and-Bubbles-1988-ceramic-106.7-x-179.1-x-82.5cm.jpg) intending on saving out the picture, Firefox ( or so it appears) forces the user to save it as webp, instead of its actual format, as you can see from the URL. Granted, I got to that photo in the first place from Google image search but spawned it into an independent window, which should occupy a separate memory space and not reference a previously cached file. While i get the primary application is to allow for multiple res versions while referencing only one file, this behaviour is pointless, irksome and serves no practical purpose when accessing the asset with an explicit URL, plus it puts unnecessary and Big Brother-ish barriers up for the less savvy. I solved the issue ultimately, but who is at fault here? Is this a function of Firefox or of the CDN where it's hosted?

Hi,

how can i allow flash if i open the Site without will be asked? I have set this in the policies.json. This is currently for testing.

"FlashPlugin": {

     "Allow": ["https://helpx.adobe.com/flash-player.html"],
     "Default": true,
     "Locked": true
   },

But I always have to allow it extra.

And the second question: Can I hide the "Menu" button via policies.json?

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.

When I click the "Add to browser" option on findfind.it (https://www.findfind.it) it used to ask me whether i want to add a new search provider. Now if I click it nothing happens anymore.

How can I add it to my search engines?

My system is freshly installed Win 10 with firefox being the only program on this computer.

How do I change, or is there a way to stop the browser from going back a page when i press delete too many times on a box or I haven't managed to click where I thought I had?

After I open the bookmarks menu, how do I get the sidebar to automatically close after I have selected and moved to that new website ? I know I can click on the X, but isn't there a way for it to just disappear once I've moved to a new site ?

In settings I've found font settings. My default font is DejaVu (Serif, Sans, Mono)

After changing font (type and size) noting is going on. Even after restart. I disabled option to let wep pages set their own font.

The most important thing for me is to have working "Minimal font size".

To sum up. I can change everything in advanced font settings but there is no result on web pages.

In seems in the last month, the ability to open links in a new tab by middle-clicking has been removed by default. I was able to get it to work in Windows (but I don't remember how), but not in Ubuntu. I've got browser.tabs.opentabfor.middleclick set to true in the about:config. I've also tried restarting with all the add-ons disabled.

Since last update several keyboard shortcuts no longer work. I find them easier than using a mouse often. Two that are most annoying at not working is Ctrl-T to open a new tab Ctrl-C to copy. That now opens developer tools This all started with last update. Does anyone know how I can restore those keyboard shortcuts?

Anyone have any idea who would make a common keyboard shortcut like the one for copy do something different. Do these people not use computers?

I hope this is appropriate here. If not, please direct me to where it is.

As new releases of Firefox (and Thunderbird too) come out, a constant question for me is whether the add-ons that are important to me (I use a lot) will be compatible with the new release. It would help if

(1) The Add-Ons web site always allowed me to specify release and OS. Sometimes that is allowed, sometimes not.

(2) The Add-Ons web site allowed me to specify a release before which I don't want to see add-ons listed.

(3) The Extensions page in Firefox allowed me to ask which of my extensions (enabled and/or disabled) are supported/not supported in a specified future release.

(4) When Firefox wants to install a new release, it reported on extensions that would become incompatible and always asked my permission to go ahead.

It probably would not be necessary to do all of these things, but I included them all because I don't know which are the most practical.

Videos on some websites like PanBaidu cannot be loaded, adivising me to install the flash plug-in which r already installed.So i wonder how to fix the problem? I also want to play the video with the speed x 2，but i cannot even load it. Could u please tell me what to do？thx！

Duckduckgo Privacy Essentials Firefox add-on, prevents "Today on AOL" from displaying. "Today on AOL" flashes briefly before displaying a blank page when the Firefox add-on is enabled.

All i wanted to do was move some favourites from one folder to another, no problem you would think...... Wait till you click the II/ tab , it decides to show some total crap thats not linked to your own favourites, but rather takingthe route of Microsoft ( Which is now unfortunetly my new browser ) ..

Why complicate things ?

Why not leave it in folder format, drag and drop

so unhappy as i wanted to avoid MSFT :(

Please dont rep[ly with did you read " XXX " and did you try " XX " ....

yes i did and its crazy complicated, if you want a demo of how to move a single file from folder to folder then i can show you, but until you sort this i am out ......

Why add-ons won't start with Firefox? Every time I need to manually disable and enable extensions Privacy Badger, uBlockOrigin (Privacy out of the box extensions) for it to be working, that is, they don't work upon start up. I have deleted the .mozilla folder in my Linux machine to reset firefox and it starts with add-ons only one time; when starting a second time, add-ons don't appear in the toolbar yet they are "enabled" but not working. As previously stated, I need to enable them manually.
