I never heard of Yandex.
I hope that someone will take on the effort to implement the code in a standard browser for IPhone, without the hassle and associated risks of using an obscure browser.
In case, I will use that extension from desktop only.
How about firefox on ios? Is the extension feature of firefox does not available on ios? Firefox on androids has extensions too so i will assume it will work on both os.
Negative.
As I tested on babo's thread (linked
here) Firefox doesn't allow extensions on iOS.
I managed to get one extension working, applying the same method with the MeritUI, but failed miserably.
