worked fine for years - Aug/15/2022 got internet speeds below 1MB/s! slowed down everything on FireFox.

Absolute crap. Doesn't work.

خیلی داغون هستش .
وقتی فعال باشه هیچ سایتی باز نمیشه چه برسد به سایت های فیلتر شده.

It is very dilapidated .
When it is active, no site will open, let alone filtered sites.

Works Okay. But only problem (or say nuisance) is, it gets removed of its own every 15-20 hours. no reason no logic just vanishes from addon list. and you just have to keep reinstalling. one more thing noticed, just found that it crashes my whatsapp web & all google sites (viz. gmail, Gsearch, & even youtube) I need to exit from firefox. clear cache & then by restarting only i could use any google related site. Strange ! for now I have uninstalled browsec. will check in future. Hope dev team can find a solution to this.

中国无法使用，不是免费 Not available in China, not free

I was using Browsec VPN to connect to a UK server from the US. After disconnecting VPN my FB was in Cyrillic; the Russian-region alphabet.
Following the reloading of the page, it appeared to clear... but now I'm going to be running diagnostics to make sure nothing untoward is happening after uninstalling the extension.

Free version works, but too slow. I see no reason to buy it

I have used the free version of Hoxx for many years and it was decent but over the last few months they removed all the servers we can access, it's down to 3, not the 50 they say on their web site. Getting greedy, it's a shame. Was ok, not any more.
In a nutshell - Don't bother!

Works very well although if streaming from UK's 4OD site there is a little buffering. But if you disconnect, you still get to watch the show as if connected and without the streaming issue. I've also noticed that the ads that you have to view watching with a VPN add-on like Hoxx are not there.
