according to the add-on page in Settings, the AdBlock Plus add-on is enabled in my browser, but it doesn't appear to be working. so I am trying to access the menu options to control it. to do that, I need to add the icon to my toolbar.

this article: https://support.mozilla.org/bm/questions/955157

explains two methods:

1. go to Settings --> Customize Toolbars, and drag the icon to the toolbar. this doesn't work, because the icon is not there to be dragged (even after I restore defaults).

2. go to the View Menu --> Toolbars --> Add-on Bar and move the icon from one toolbar to another.

quite apart from the fact that it took me two days to figure out how to get the View Menu to appear, that procedure doesn't work either because after View Menu --> Toolbars --> the Add-on Bar is not listed.

can someone please tell me what I'm doing wrong.

thank you,

Since yesterday I am getting this "Did Not Connect: Potential Security Issue" error on every sites that I have tried to visit. Even on well known secured sites like https://drive.google.com is inaccessible while my Chrome and Edge is working fine. Any solution?

A website I use to move money - getting message telling me cookies is blocking 3rd party cookies. and I need to enable 3rd party cookies. I go to settings in firefox and for the information to set settings to enable cookies 3rd party they do not work. They tell me to check and uncheck boxes that I do not even have for setttings. I never had this problem before until Jan. of 2022. I have to use a different browser to get to the website and complete my task. There is something in the Firefox browser or they made changes/updates. Need step by step instructions. NEED TO TALK TO SOMEONE.

Periodically, randomly is all I can say, a message window opens when I power on with a statement about "UpdateBrowserForApp" having stopped working; and then I'm given options to close the program, etc. See attached screenshot.

Firefox is the only browser I use. Is this message from Firefox or does it mean I should do something related to Firefox?

Thanks for whatever info or help you can give. Lee

I've got a legacy transformer laptop with an integrated wacom-type sensor screen. Despite all shortcomings of it's age, the laptop's got class.

The main web browser installed is Firefox ESR. In tablet mode, control was handled by the Windows - mouse-like drag'n'drop, marking, but with added scrolling gesture by swinging quickly up and down. Using it in the tablet mode is actually very practical.

Recently, after updating from 91 to 101, browser started to interpret the pen as a finger, controls became clumsy and frustrating. The only way of turning finger gestures off, parameter gestures.enable_single_finger_input described in that question (https://support.mozilla.org/en-US/questions/973974) had no visible effect. Have fallen back to 91esr, but this is obviously just a temporary solution. Is there any way to add force-disable parameter or something?

UAC notification pops up every time I try to open Firefox since last update on 5/5/22. I've deselected all options that run the program as an administrator, but it still shows up every time. I've checked that no admin is selected in both the shortcut I use and in the program itself. Any suggestions?

My IDM extension no longer seems to be the default downloader. Downloads now come via the native Windows (8.1) downloader. Can you suggest any way of resolving this issue?

I have Firefox version 97.0.2 (64 bit) for Windows. Lately, every time I start up the browser, it's trying to install an update. I haven't had this problem before with Firefox (and I've been using it for several years now). Is there something I need to do to stop this?

I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

I have had 2 sites produce this error box in place of the target Web Site (See Picture). I have read previous topics about this and have followed the instructions with no positive results. FYI, clearing the web site's cookies, clearing Cache and disabling Hardware acceleration.

The first was https://www.walmart.com. After leaving a "Feedback" 2 weeks ago it appears as if they were able to fix the problem. However, the site is not as important as my Medicare PPO provider. I tried loading previous versions of Firefox, but that did not help.

In both instances the LOL "support" people's response was to try a different Browser. So, I reluctantly loaded Google Chrome and it worked perfectly. From my perspective, this eliminates everything to do with my machine setup.

I searched for an official portable version of firefox and one of the first results was this https://support.mozilla.org/en-US/questions/1247235 anyways this seems dissapointing since he says we should only download from official sources and at the same time there is no official portable version, can i be honest.. this sucks. You know time passed since that thread was created (3 years...) but still no offfical version, why?

So it seems to most known source for firefox portable is this site: https://portableapps.com/apps/internet/firefox_portable I know you don't represent this website but still i have to ask how secure is it?

Also, how are chances mozilla will work on a portable official version? any plans?

Since the latest version of Firefox I cannot simply open attachments to Yahoo emails. I have to waste time to download and save the attachments before I can view them. How can this be fixed? Or, how can I download a previous version of Firefox and not have any updates?

Hi, I spent several hours trying just to change the color of the downloads icon (thought it would take me 1 minute). First I tried to do it myself, then searched the internet. From what I found on the internet, some stuff doesn't work, some works partially and in an unexpected way, most of it is difficult to understand and modify. Finally I give up. Please, is it possible to make white the download pie and the arrow thing (when the download is finished). That's all I ask for. If possible, without using the var-- stuff, just using fill: or filter: or some other straightforward functions.
