Mozilla Lifts Firefox VPN Data Cap Through August, Releases 151.0.4 Bug Fixes
Mozilla has lifted the bandwidth cap on Firefox’s free built-in VPN through Aug. 31, 2026, expanding access to 28 countries while simultaneously shipping a stability update for the browser.
The promotion removes the service’s standard 50GB monthly data limit for the summer period, according to a Mozilla blog post published this week.
Firefox VPN Goes Uncapped for Summer
Mozilla said it aimed the offer at travelers connecting through public Wi-Fi at airports, hotels, and train stations during the summer months.
Under the promotion, eligible users can select VPN exit points across North America, Europe, Asia, Africa, and Oceania — a significant expansion from the service’s usual limited location list.
Available countries include the United States, United Kingdom, Canada, Germany, France, Australia, Japan, Singapore, South Africa, and roughly 18 additional markets spanning multiple regions.
The VPN requires no separate client installation and no additional account setup, operating entirely within the browser itself.
Mozilla also said users can disable VPN protection on a per-site basis directly from the browser interface, addressing a common friction point where some websites block or degrade service when they detect privacy tools.
After Aug. 31, Firefox will revert to the standard 50GB monthly cap and its regular selection of server locations.
Version 151.0.4 Targets Windows Stability
Alongside the VPN announcement, Mozilla released Firefox 151.0.4, a maintenance update targeting several bugs affecting Windows users.
The release fixes an issue that caused Firefox to become unresponsive when users navigated pages using the browser’s back and forward buttons, according to the official Mozilla release notes.
A separate fix addresses a problem where Firefox incorrectly fell back to software rendering on certain older GPUs — a regression that reduced graphics performance for affected users.
The update also patches a Windows crash tied to accessibility services and corrects a UI bug that caused text input fields to display an erroneous resize handle.
None of the fixes introduce new features, but browser stability patches often carry more practical weight for everyday users than capability additions.
Mozilla said it plans to release Firefox 152 on June 16, suggesting the next round of changes is already close.
Nightly Picks Up an Animated Logo
Firefox Nightly — the browser’s experimental pre-release channel where Mozilla tests features before they reach the general public — received a smaller but visually notable change this week.
The Nightly build’s logo now animates when a user clicks it, according to reports from users running the channel.
The change carries no functional weight but signals ongoing attention to the browser’s fit and finish at even the earliest development stage.
Mozilla has announced several other Firefox changes in recent days, including confirmed plans to add built-in ad blocking, Vulkan Video support slated for Firefox 153, and new World Cup widgets and wallpapers for the browser’s New Tab page.
Vulkan Video is an open standard for hardware-accelerated video decoding and encoding, part of the broader Vulkan graphics API maintained by the Khronos Group.
