My Firefox extension

I have been using Firefox for a while. I tried to install several extensions and it is quite easy to use:

Flashgot. Download is naturally rare.
PDF download. If you click a PDF link directly, Adobe's plug-in will be "smart" to open the PDF file in Firefox, so Firefox will not respond for a long time. After the extension is installed, click the PDF link and a dialog box will pop up asking whether to download or directly view it.
Flashblock. Does flash on the webpage look at it or not? It will inevitably affect the speed, especially for some abnormal websites with more flash. What should I do? Use flashblock. It will be indicated by a GPS symbol in the Flash display area of the application. It is not downloaded beforehand. You can click to view or view a flash. Convenient?
Session Manager. It's about to shut down, but there are still a lot of webpages on the Firefox side, so it would be nice to save them. Instead of saving the content of the entire web page, you can organize these open links. Next time I can open them all at once. I started to try session save. It either saves this session every time I close Firefox, or does not save it every time. It is not very nice. With session manager, you can set a lot of settings and record the previous several closed web pages. If you accidentally turn the page off, you can recover it from here. But the author can say that this extension should not be used with Crash recovery, session saver or tab mix plus.
Gmail manager. Good stuff. You can manage multiple Gmail accounts. I have multiple Gmail accounts. In addition, you can open a new tag and use an account to write emails. I used to envy Gmail notifier in windows. It turns out Firefox can be used with extensions.

There are still many good extensions to be explored. If you have any requirements, go to Mozilla update China.

By the way, the Noia topic is quite interesting.
