To keep your browsing experience fast, reliable and secure, Firefox will not activate NPAPI plugins such as Adobe Flash by default. Instead, Firefox lets you choose whether or not to allow the plugin to run on a website.
How to click to activate works
If Firefox blocks a plugin, rather than seeing content, you"ll see a message prompting you to click to run the plugin, such as Adobe Flash.
On some sites, you"ll see just a blank rectangle, and the plugin notification icon will appear toward the left end of the address bar.
If you click the message or the notification icon to activate the plugin, Firefox will prompt you with these options:
- Allow: Activates the plugin on the website, only for a single visit. To automatically activate the plugin for all future visits to that site, check the Remember this decision checkbox.
- Don't Allow: Dismisses the notification prompt without activating the plugin.
If you click to activate and allow the plugin, the missing content will load normally. (If it doesn't, click the reload button in the toolbar to reload the page and try again.)
When is it okay to activate a plugin?
In a situation like this, you can make a smart choice depending on your current task:
- If you"re using a trusted site like a special site for your work or school, you might feel safe enough to enable a plugin in order to view the site's content.
- If you don"t fully trust a site, for example, you arrived at the site by following a link, you probably don't want to activate the plugin.
Can I set a plugin to always activate?
To set Firefox to always activate a plugin:
Click the menu button , click Add-ons and select Plugins . Find the plugin and click the ellipsis (3-dot) icon, then select Always Activate from the drop-down menu. This will activate the plugin automatically and you will no longer get messages to run the plugin.

A little earlier, I wrote about the problem with Adobe Flash Player in Mozilla Browser. At this point, we can probably say that the problem is solved.
As a result of the tests, I came to the conclusion that Adobe Flash Player is to blame for the poor performance of the video. Not Youtube, which, by the way, apparently, partially or completely, abandoned Flash and switched to HTML5 in January of this year, not Mozilla browser Firefox, namely Adobe Flash Player. Of course, the crookedness of the Adobe programmers is surprising, but what can you do?
The solution to problems with video playback is as follows: using a brute force method, select the appropriate version of Adobe Flash Player. Versions, there is no need to talk about this, you need to take them from the official Adobe website, otherwise you can get the situation.
In my case, Adobe Flash Player 10.3, dated April 2013, worked. This is such nonsense: in order for embedded videos on websites to work properly, I had to roll back the version of Flash Player from 17 to 10.
The issue was resolved by searching through flash versions. I set it to 16th - the glitches remained. I set it to 15th, 11th - there were still glitches. And that’s how I got to version 10, with which everything works fine.
The only "BUT". We all know that older versions of Flash Player have vulnerabilities and therefore, it is up to you to decide whether to work with older versions or not. Just in case, read how to do it correctly.
Well, if you decide to do this, then after installing the old version of Flash Player, be prepared for the fact that when you go to any site that requires Flash, you will see the following message:
Updating Flash Player will most likely lead to its inoperability again, so there is only one way out: to allow and remember the operation of Flash Player for each specific site. Allowed, it will not remind you of itself next time.
You can enable and remember by clicking on the red icon (in the green circle on the screen)
Any user can push it. Even the most careful and pedantic person who monitors updates of important programs for his personal computer is not immune from errors in the system or incorrect operation one or another utility.
If Flash Player doesn't work in Firefox, here's how to fix it:
Go to the official website technical support Adobe products and look in the Flash Player Help section.
In the new tab that opens, an easy-to-understand description will appear in five steps for checking and installing the required module.
Step one - check relevance software Adobe Flash Player. If everything is fine, a similar sign will appear; if not, the appropriate information will be displayed.
The second step, if there are problems, is to install Flash Player on a custom Personal Computer. To do this, you need to follow the appropriate link.
The third step will be the installation of the program itself.
Step four is to activate the plugin. The developers' website presents detailed instructions to the most popular search engines, as for operating system Windows and Mac OS. Recommendations for Mozilla Firefox similar to recommendations for Google browsers Chrome and Opera. If you learn how to fix such errors in one Internet browser, there will be no problems with others.
To do this, you need to go to the settings menu in the “Add-ons” section, then to the “Plugins” tab and make sure that the module “ Shockwave Flash» is present and active.
Also useful are two features for blocking dangerous and intrusive Flash content and additional protection from Adobe. By clicking on the “More details...” links you can familiarize yourself with the advantages of these two functions.
